Title
MISP: Unescaped HTML Injection in PDF Report Element Rendering
Summary
MISP contains an HTML injection vulnerability in the MISPElementHTMLFormatterTool component, which is responsible for rendering MISP element references (attributes, objects, and tags) into inline HTML during PDF report export via the convert_markdown_to_pdf module. The attribute(), objectAttribute(), object(), and tag() methods interpolated user-controlled fields (attribute type, attribute value, object name, object relation, tag name, tag colour, and tag text colour) directly into HTML templates without applying HTML entity encoding. An authenticated user with the ability to create or modify MISP attributes, objects, or tags could embed arbitrary HTML markup in these fields. When a report containing such elements was exported to PDF, the unescaped content was rendered as live HTML rather than inert text, potentially injecting script tags, breaking the document structure, or altering the visual content of the exported report. Additionally, the attribute() method contained a template with hardcoded sample values ("domain-ip" and "google.com") instead of format placeholders, meaning every plain attribute reference in a PDF displayed the sample text rather than the actual indicator value, constituting a data-integrity defect in the exported document. The vulnerability requires an authenticated actor with write access to MISP elements and a subsequent PDF export of a report referencing those elements. The security impact is primarily to the integrity of the exported document and, depending on the HTML-to-PDF rendering engine, potential execution of injected markup during the conversion step.

fix: [event-report] Render and escape MISP element references | 300efd40407c… |
Fix summary
The fix applies HTML entity encoding (via the h() helper, which wraps htmlspecialchars with ENT_QUOTES and UTF-8) to every user-controlled value interpolated into the HTML templates in the MISPElementHTMLFormatterTool. This ensures that attribute types, values, object names, relations, tag names, and colour values are treated as inert data and cannot inject markup or break out of the surrounding span/style context. The hardcoded sample values in the attribute() template are replaced with proper %s format placeholders so that the actual element data is rendered. Comprehensive unit tests are added to verify both correct rendering and escaping of hostile inputs across all four formatter methods.
Patch summary
In MISPElementHTMLFormatterTool.php: (1) the attribute() template's hardcoded 'domain-ip' and 'google.com' strings are replaced with %s placeholders; (2) all sprintf arguments in attribute(), objectAttribute(), object(), and tag() are wrapped with h() to HTML-encode the interpolated values (attribute type, value, object name, object_relation, tag name, colour, text_colour). A new test file MISPElementHTMLFormatterToolTest.php is added with 123 lines of PHPUnit tests covering: correct rendering of real values, HTML escaping of hostile payloads (script tags, span-breaking sequences, CSS attribute breakout via quotes), foreign-tag detection, and placeholder behaviour for objects without attributes.
CVSS rationale
AV:N: MISP is a network-accessible web application. AC:L: The attacker only needs to create or modify a MISP element with a crafted value; no race conditions or special timing are required. AT:N: No manipulation of the attack target is needed. PR:L: The attacker requires an authenticated account with permission to create or modify MISP attributes, objects, or tags. UI:N: The victim performs a normal, expected action (exporting a report to PDF); no unusual interaction is required to trigger the rendering of the injected content. VC:N: The primary impact is on the output document, not on reading confidential system data. VI:L: The integrity of the exported PDF is compromised by injected markup or incorrect data (hardcoded sample values). VA:N: No denial-of-service impact is evident. SC:N: No confirmed cross-system confidentiality impact. SI:L: The integrity of the exported document (a secondary asset) is affected; injected content could mislead readers or, if the PDF renderer executes scripts, affect the rendering environment. SA:N: No security-relevant impact on other systems is established by the evidence.
Weakness rationale
- CWE-79 User-controlled MISP element values (attribute values, object names, tag names, tag colours) are interpolated into HTML output without encoding, allowing injection of arbitrary HTML markup into the rendered document. Although the output target is a PDF rather than a browser page, the mechanism is identical to stored XSS: untrusted data is embedded in an HTML context without neutralization.
- CWE-116 The root cause is the absence of output encoding (htmlspecialchars) on all interpolated values in the HTML template strings. The tag() method additionally failed to escape colour values that are placed inside a CSS style attribute, enabling attribute-breakout injection.
Assumptions to verify
- The HTML-to-PDF rendering pipeline (convert_markdown_to_pdf) is assumed to render the generated HTML in a context where injected markup could be interpreted (e.g., headless browser or HTML-aware converter); if a purely static renderer is used, the impact is limited to document corruption.
- The attacker is assumed to have an authenticated MISP account with write access to attributes, objects, or tags; the specific role or permission level required is not stated in the patch.
- The exact fixed version is not specified in the patch metadata; the tag boundary (v2.5.46, 187 commits before the fix) indicates the fix post-dates v2.5.46 but the precise release is unknown.
- UI:N is assigned on the assumption that triggering the PDF export is a normal, expected user action and does not constitute a special interaction requirement beyond routine use of the application.

Title
MISP Event Template Instantiation Bypasses Sharing Group and Tagging Authorization
Summary
Affected versions of MISP do not consistently enforce the acting user's authorization when instantiating event templates.
For templates using distribution = 4, the template can specify a sharing_group_id. The instantiation path passed that value into event creation without verifying that the user instantiating the template was actually permitted to use the selected sharing group. The commit notes that Event::_add() only performed its own sharing-group authorization in another code path, leaving template instantiation able to write the identifier directly.
The same instantiation path also attached template-specified tags without checking the user's normal tagging permissions. In addition, it hardcoded local => 0, meaning tags marked local_only could be attached globally and consequently propagate through synchronization or export, contrary to their intended restriction.
The fix adds explicit SharingGroup::canUse() authorization for the acting user, applies the same tag-modification checks used by normal event tagging, and ensures local_only tags are attached locally.

Title
Use of Hard-coded Credentials in drEryk Gabinet
Summary
DrEryk Gabinet before 11.5.0 uses hard-coded API credentials in its ticket reporting component. These credentials can be used to authenticate directly to the ticket system API. This allows an attacker to perform privileged operations beyond what is offered by the application, including reading and modifying tickets.

Title
Path traversal in Pandora archive extractor allows arbitrary file writes outside the extraction directory in pandora analysis
Summary
Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory.
An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process. Successful exploitation could result in unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten.
The vulnerability is addressed by resolving each extraction destination path before writing and verifying that it remains below the expected extraction directory. Extraction attempts resolving outside this directory are rejected and reported as path traversal attempts.

CVE-2026-87827 (GCVE-0-2026-87827)
Vulnerability from cvelistv5 – Published: 2026-09-09 10:54 – Updated: 2026-09-09 12:28Title
KGUARD DVR unauthenticated remote command execution vulnerability
Summary
Certain KGUARD DVR devices running vulnerable firmware expose a system command execution service on all network interfaces without requiring authentication. A remote unauthenticated attacker with network access to the affected service can execute arbitrary system commands on the device, potentially resulting in complete compromise of the DVR.
The vulnerability is known to have been exploited in the wild by the Mirai_ptea (Rimasuta) and Mirai_aurora botnets for malware propagation and subsequent DDoS activity. The vulnerability was reported to affect firmware dating from 2016, while firmware released after 2017 appears to mitigate the issue by restricting the affected service to the localhost interface (127.0.0.1) instead of exposing it on all interfaces (0.0.0.0).
The affected-device list reported by Netlab includes many D1004NR, D1008NR, D1016NR, D1104, D1104NR, D1108NR, D1116NR, D1132NR, D2116NR, D97xx, D98xx, and D99xx variants and several associated hardware revisions
The exploit is included in some version of rapperbot and exploited in 2026. This assignment has been made to document the active exploitation and lack of documentation from the vendor.

CVE-2026-86452 (GCVE-0-2026-86452)

Title
MISP Unauthenticated Mail Endpoints Allow Unbounded Storage Consumption and Request Flooding
Summary
Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting.
The users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle.
The fix adds:
*
a maximum email input length of 1024 bytes;
*
email-format validation before persistent work;
*
a per-source pre-authentication request budget;
*
HTTP 429 responses when that budget is exceeded;
*
a 15-minute cooldown for API-access request emails;
*
POST-only handling and CSRF protection for the API-access request endpoint.
The new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts.

Title
MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects
Summary
Affected versions of MISP allow authenticated users to retrieve object-reference records by UUID through EventGraphTool::get_reference_data() without first checking whether the requester is authorized to view the object the reference belongs to.
The vulnerable code queried ObjectReference.uuid directly and returned the matching row whenever it existed. Because no parent-object ACL was applied, a user who knew or obtained a reference UUID could retrieve information associated with an object outside their normal access scope. The commit explicitly states that any object reference could be returned by UUID without authorizing its parent object.
The fix retrieves the referenced object's object_id and calls fetchObjectSimple() with the current user. If the user cannot access that parent object, MISP now returns NotFoundException instead of exposing the reference.

Title
MISP Dashboard Organisation Widgets Bypass Organisation-Index Restrictions and Expose Hidden Organisation Data
Summary
Affected versions of MISP contain inconsistent authorization checks across dashboard widgets that display organisation information.
Several organisation-related widgets did not honor Security.hide_organisation_index_from_users. As a result, authenticated users without the perm_sharing_group permission could enumerate organisations even though the normal organisation index was intentionally hidden from them.
The affected widgets included paths that:
*
returned organisation names and identifiers;
*
could expose additional organisation database fields through JSON export because unrestricted find('all') queries fetched full rows;
*
accepted limit=0 or negative values in a way that could effectively remove the result limit and return the entire organisation table.
A related organisation-contributor leaderboard also ignored the same visibility setting. Its handler counted Event.orgc_id across the entire event table and mapped those IDs to organisation names, revealing every organisation with events regardless of whether the caller could see any of those events. The fix withdraws this widget entirely for users who lack organisation-index visibility.

Title
MISP Dashboard Button Widget Allows Stored XSS via Unsafe javascript: and Backslash URLs
Summary
Affected versions of MISP insufficiently validate URLs used by dashboard widgets, particularly the Button widget.
The widget's URL is stored configuration controlled by a user. The previous renderer considered a URL safe if it appeared relative or if its parsed hostname matched the configured MISP hostname. That logic failed to reject dangerous schemes and URL forms that browsers normalize differently from PHP's URL parsing.
As a result, values such as javascript: URLs or backslash-based authority forms could reach the generated anchor's href and execute script or navigate to an attacker-controlled origin when another user interacted with the widget. The upstream commit describes the issue as:
“javascript: and backslash URLs reached the href (stored XSS)”.
The fix routes widget URLs through a shared DashboardURLValidator, rejects dangerous schemes, raw backslashes, control characters, and unauthorized absolute origins, and validates the URL both in the widget handler and renderer.

Title
MISP Insufficient Outbound URL Validation Allows SSRF and Credential Disclosure via Feed Redirects and TAXII Discovery
Summary
Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality.
In feed processing, redirects were followed without validating the redirect scheme or destination. The original request headers were reused across redirect hops, meaning authentication headers or API credentials configured for a feed could be forwarded to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results to prevent re-resolution after validation.
The TAXII discovery endpoint had a related incomplete SSRF defense. It used gethostbyname() and compared the result against only a few literal addresses. This missed cases including IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and potentially multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator.
Together, these commits harden MISP's outbound URL handling against alternate-address representations, DNS-related bypasses, unsafe redirects, internal-host access, and cross-host credential forwarding.

Title
MISP Dashboard Organisation Picker Exposes Hidden Organisation Metadata to Unauthorized Users
Summary
Affected versions of MISP expose organisation metadata through the dashboard organisation picker without applying the same visibility restrictions enforced by the normal organisation index and per-organisation view.
The affected endpoint returned fields including:
*
organisation ID;
*
UUID;
*
name.
When Security.hide_organisation_index_from_users was enabled, normal organisation enumeration was restricted, but the dashboard picker still queried all organisations. This allowed authenticated users to discover organisations that should have remained hidden from them.
The fix calls Organisation::createConditions($this->Auth->user()) and appends the resulting ACL conditions to the picker query. Ordinary users are thereby limited to organisations associated with events or proposals they can already see, plus their own organisation, while users with the appropriate sharing-group privilege retain broader visibility.

Title
MISP Dashboard Template REST API Exposes Template Owner Email Addresses to Unauthorized Users
Summary
Affected versions of MISP inconsistently enforced email-address visibility in DashboardsController::listTemplates().
The query always fetched User.email, while redaction happened only inside the non-REST rendering branch. As a result, the same authenticated user who saw redacted data in the normal HTML interface could request the REST/JSON representation and receive template owners’ email addresses without the intended privilege check.
The fix moves the decision to a centralized User::canSeeEmails() authorization helper. Email addresses are now fetched only when the requester is a site administrator or the instance explicitly enables Security.disclose_user_emails. The same helper is also reused by other dashboard widgets to keep email-disclosure policy consistent.

Title
MISP Missing Authorization in Cryptographic Key View Exposes Signing Keys from Protected Events
Summary
Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view().
The vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as:
*
type
*
key_data
*
fingerprint
but did not fetch or authorize the associated parent event first.
The upstream commit explicitly states that cryptographicKeys/view could return a protected event’s signing key to any authenticated user.
The fix adds parent_id and parent_type to the lookup and then enforces authorization through the associated event using fetchSimpleEvent($user, parent_id). If the parent is not an Event, access is limited to site administrators.

Title
MISP User Homepage Validation Allows Authenticated Open Redirect via Protocol-Relative URL
Summary
Affected versions of MISP validate the user-configurable homepage by checking only whether the supplied path begins with /. That check is insufficient because protocol-relative URLs such as //attacker.example also begin with / but resolve to an external origin in browsers.
The vulnerable homepage value can be stored as a user setting and later used by the post-login routing logic. The commit explicitly identifies //attacker.example as a payload that passed validation and was emitted to the Location header after login.
The fix introduces a shared InternalRedirectValidator that rejects URLs containing a host, scheme, userinfo, unsafe leading // or /\, malformed URLs, and control characters. It also revalidates homepage settings on read so legacy or internally written unsafe values cannot bypass the new storage-time validation.

Title
MISP Missing Authorization on Template File Upload Allows Authenticated Disk Exhaustion
Summary
Affected versions of MISP allow any authenticated user to access TemplatesController::uploadFile() because the ACL entry for templates/uploadFile used the wildcard *. This bypasses the intended role restrictions applied to neighboring template-management operations.
The upload handler accepts arbitrary content with only minimal checks and writes it into app/tmp/files/. A low-privileged or read-only user can therefore repeatedly upload files and consume server disk space without requiring perm_add or perm_template. The fix changes the ACL requirement from * to perm_add.
The commit also rules out stronger impacts: uploaded files receive random names, path traversal/predictable overwrite is not available, the temporary directory is outside the web root, and the files are not directly served over HTTP. Therefore, the issue should not be described as arbitrary file overwrite, stored XSS, or RCE.

The fix changes the ACL requirement from * to perm_add.\n\nThe commit also rules out stronger impacts: uploaded files receive random names, path traversal/predictable overwrite is not available, the temporary directory is outside the web root, and the files are not directly served over HTTP. Therefore, the issue should not be described as arbitrary file overwrite, stored XSS, or RCE.\n\nVersion affected:\u00a0\u22642.5.45"

Title
MISP Freetext Feed Preview Improper Authorization Exposes Restricted Event and Feed Information
Summary
Affected versions of MISP contain improper authorization checks in the freetext feed preview functionality. The preview performed correlation lookups against attributes from events without applying the requesting user's ACL, allowing restricted event correlations and associated event information to be exposed to users who could not otherwise access those events. The vulnerable queries were scoped only by attribute values and deletion status rather than MISP's event, organization, sharing-group, attribute, and object-level access controls.
The same preview functionality also returned cross-feed correlation information without properly restricting the feed list to feeds visible to the caller. This exposed metadata for feeds that were not marked lookup_visible; one affected response additionally included the configured feed URL even though that value was not required by the feature.
The fixes apply the caller's ACL to attribute correlation searches, remove feed URLs from correlation results, restrict cross-feed results according to feed visibility, and correct host-organization ID comparison so the authorization rules are applied consistently.

Title
The Continuous Glucose Monitoring Service's Record Access Control Point (RACP) write handler `memcpy`s the entire attacker-supplied ATT write value into a fixed 20-byte BSS buffer.
Summary
A buffer overflow in the Bluetooth Continuous Glucose
Monitoring Service (CGMS) Record Access Control Point (RACP) write handler
allows an authenticated BLE peer to overflow a 20-byte static buffer into
adjacent BSS memory. The exploitable impact cannot be predetermined - it
is entirely dependent on the linker-assigned BSS layout of the specific
firmware build, which may vary.

Title
nRF54H20: MCUBoot can be tricked to executing unauthenticated code
Summary
When using the Direct XIP
update strategy, the main application image starts other cores (i.e. radio
core), based on the currently active slot without additional verification. The
MCUboot in the bare (upstream) configuration assumes that if there is at least
a single slot for each image available, the system is bootable and continues
the boot process. This may lead to a situation when MCUboot picks different
slot for different images (i.e. (a) for the main application and (b) for the
radio image), boots the main application (from slot (a)) that afterwards starts
the radio image by providing an address of the unauthenticated slot ((a)
instead of (b)).

Title
MISP UiBeta Collection View Bypasses Event ACL, Exposing Unauthorized Event Data
Summary
MISP's UiBeta theme collection view (app/View/Themed/UiBeta/Collections/view.ctp) performed a secondary query of member events by UUID without applying the caller's access control list (ACL). The CollectionsController::view() action correctly resolved collection element UUIDs through Event::fetchSimpleEvents($user, ...), which enforces per-user event ACL. However, the view template independently re-queried the same UUIDs using only an Event.uuid IN (...) condition, omitting the createEventConditions() authorization filter. Because collection element UUIDs are stored without server-side authorization against the referenced event (CollectionElementsController::add() accepts whatever UUID the collection owner posts), an authenticated user with view access to a collection could retrieve full details of events they are not permitted to read. The exposed data included event identifiers, info, dates, timestamps, creator organization, all event tags, and galaxy clusters (the latter attached via a cluster-scoped rather than event-scoped ACL check). This constitutes an authorization bypass at the presentation layer, allowing horizontal privilege escalation across event boundaries within the MISP instance.

"cvssRationale": "The vulnerability is exploitable over the network (AV:N) via the MISP web interface. Attack complexity is low (AC:L) because the attacker only needs to view a collection whose elements reference events outside their ACL; no race conditions or special timing are required. No attack target manipulation is needed (AT:N). The attacker must be an authenticated MISP user with at least view access to a collection (PR:L). No user interaction is required beyond normal browsing (UI:N). The impact is high on the confidentiality of the vulnerable component (VC:H) because full event metadata, tags, and galaxy cluster data are exposed to unauthorized users. There is no integrity or availability impact on the vulnerable component (VI:N, VA:N) and no impact on external components (SC:N, SI:N, SA:N) since the exposed data resides within the same MISP instance.",

SSH session privilege manipulation via a crafted username in Mikrotik RouterOS
Summary
RouterOS contains an argument-handling flaw in the SSH login
path involving usernames that begin with a prohibited character, allowing for the trusted RouterOS policy mask to be changed, leading to privilege escalation. Exploitation requires an unauthenticated SSH session to reach the RouterOS login helper.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)

Title
Unauthenticated file read in Mikrotik RouterOS
Summary
RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace and disclose root-owned files, including configuration stores containing credentials.This issue affects only 7.x branch was fixed in versions: 7.23.4 (Long-term) and 7.24.2 (Stable)

SSH Pre-Authentication Rekey State Bypass in MikroTik RouterOS
Summary
RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configuration and diagnostic data.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)

Title
TLS server impersonation possible in Mikrotik RouterOS
Summary
MikroTik RouterOS accepts malformed RSA/PKCS#1 v1.5 signatures during X.509 validation. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted intermediate and issue certificates for arbitrary hostnames, enabling TLS server impersonation.
This issue affects only 7.x branch was fixed in versions: 7.23.4 (Long-term) and 7.24.2 (Stable)

CVE-2026-67277 (GCVE-0-2026-67277)
Vulnerability from cvelistv5 – Published: 2026-09-05 20:00 – Updated: 2026-09-11 03:55Title
Kernel memory disclosure and denial of service in MikroTik RouterOS btest service
Summary
RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate unchecked, inverted packet-size interval causes unsigned integer underflow, anomalously large fragmented output, and can restart the RouterOS kernel.
This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)

CVE-2026-67276 (GCVE-0-2026-67276)
Vulnerability from cvelistv5 – Published: 2026-09-05 20:00 – Updated: 2026-09-09 04:26Title
SSH user impersonation possible in Mikrotik RouterOS
Summary
RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can supply a key with exponent one, forge a valid signature, and open an SSH command channel as the target user without the private key.This issue affects only 7.x branch was fixed in versions: 7.23.4 (Long-term) and 7.24.2 (Stable)

Summary
(Holloway) Chew, Kean Ho's Actualizer v1.2.0 and earlier contains a fail-open password validation vulnerability in the Alpha user and root user password loops of Shell/debian-minbase-install.sh. The installer invokes mkpasswd to generate yescrypt password hashes but does not check the command's return value and unconditionally accepts the result. If mkpasswd fails to generate a yescrypt hash, for example because an incompatible mkpasswd implementation or an environment without yescrypt support is used, the resulting password hash variable can be empty and the build proceeds. The resulting image can therefore contain empty password fields for the root and alpha accounts, potentially permitting passwordless authentication depending on the authentication configuration.

Title
Cross-Site Request Forgery via Attacker-Controlled REST Detection in MISP
Summary
A cross-site request forgery (CSRF) vulnerability exists in MISP due to form-security and CSRF protections being disabled based on whether an incoming request was identified as a REST request.
MISP's REST detection can be influenced by request properties such as the URL suffix or the HTTP Accept header. Because Accept: application/json can be supplied by a cross-origin page without requiring a CORS preflight, an attacker could cause a request originating from another website to be treated as REST traffic. MISP would consequently disable its normal form-security and CSRF validation even though the request was authenticated using the victim's existing browser session.
An unauthenticated remote attacker could exploit this behavior by convincing an authenticated MISP user to visit or interact with a malicious web page. The attacker's page could then issue crafted requests to susceptible state-changing MISP endpoints using the victim's privileges. Depending on the permissions of the victim and the targeted endpoint, this could allow unauthorized modification, creation, publication, or removal of data and other state changes.
The vulnerability originates from granting the form-security exemption based on _isRest() rather than on the authentication mechanism used by the request. The patch changes this behavior so that CSRF and form-security exemptions are granted only when the request actually carries a MISP API key. Session-authenticated REST-style requests remain subject to CSRF protection.
The fix also introduces support for transmitting CSRF tokens through the X-CSRF-Token header for legitimate same-origin AJAX requests. Such a header cannot normally be attached by a cross-origin page without triggering a CORS preflight, preventing it from being used to reproduce the original attack.
