CVE-2026-54394 (GCVE-0-2026-54394)

Vulnerability from – Published: 2026-06-12 20:30 – Updated: 2026-06-15 18:03

Title
MISP organisation logo path traversal allows retrieval of arbitrary PNG/SVG files
Summary
MISP contains a path traversal vulnerability in OrganisationsController::getOrgLogo. The vulnerable code builds organisation logo file paths using organisation-controlled fields such as id, name, and uuid without ensuring that the resolved file remains inside the intended APP/files/img/orgs/ directory. An attacker able to influence an organisation field, for example the organisation name, could use path traversal sequences to cause MISP to return arbitrary readable .png or .svg files from outside the organisation logo directory. The issue is fixed by resolving candidate paths with realpath() and verifying that they remain under the expected base directory before serving the file.

CVE-2026-54395 (GCVE-0-2026-54395)

Vulnerability from – Published: 2026-06-12 20:36 – Updated: 2026-06-15 17:56

Title
MISP UiBeta event index reflected XSS in advanced filter popup
Summary
MISP contains a reflected cross-site scripting vulnerability in the UiBeta event index view. The urlparams value is inserted into an inline JavaScript handler using HTML escaping inside a single-quoted JavaScript string. Because browsers HTML-decode attribute values before JavaScript parsing, a crafted searcheventinfo value can restore encoded quote characters and break out of the JavaScript string. An attacker could craft a malicious URL that, when opened by a victim using the UiBeta event index, executes arbitrary JavaScript in the victim’s browser in the context of the MISP instance. The issue is fixed by encoding the value as a JavaScript string literal with json_encode() before applying HTML escaping at the attribute layer.

CVE-2026-54396 (GCVE-0-2026-54396)

Vulnerability from – Published: 2026-06-12 20:48 – Updated: 2026-06-15 17:55
VLAI
Title
MISP AuthKey edit endpoint allows authenticated user email enumeration
Summary
An information disclosure vulnerability exists in the MISP AuthKey edit functionality. When a validation error occurs during an AuthKey edit request, the user dropdown was populated using the attacker-controlled AuthKey.user_id value from the submitted request data. An authenticated user with permission to edit an AuthKey could submit arbitrary user IDs and observe the returned dropdown data, allowing enumeration of user email addresses. The issue is fixed by deriving the dropdown user from the persisted AuthKey owner instead of the request body.

CVE-2026-54397 (GCVE-0-2026-54397)

Title
MISP event editing allows unauthorized assignment to undisclosed sharing groups
Summary
A vulnerability in MISP’s non-REST event editing path allowed an authenticated user with event edit permissions to manipulate the submitted form data and set an event’s sharing_group_id to a sharing group they were not authorized to use. When distribution was set to sharing group distribution, the non-REST save path accepted the submitted sharing_group_id without performing the same sharing group authorization check enforced by the REST edit path. An attacker could exploit this by tampering with the event edit request and assigning an event to an undisclosed or unauthorized sharing group. This could result in unauthorized use of restricted sharing groups, disclosure of the sharing group name in event listings, and unintended modification of the event’s distribution metadata. The issue is fixed by validating that the selected sharing group can be used by the current user when the sharing group is changed, and by clearing sharing_group_id when the event distribution is not set to sharing group distribution.

CVE-2026-54398 (GCVE-0-2026-54398)

Title
MISP object edit authorization bypass allows unauthorized sharing group assignment
Summary
An authorization flaw in MISP’s object add/edit handling allowed an authenticated user with object editing permissions to assign a MISP object, or attributes contained within an object, to a sharing group that the user was not authorized to use or view. When editing objects, the sharing group validation was performed against the wrong request data structure after object fields had been merged to the top level, causing the check to be bypassed. In addition, attributes embedded in objects were not individually validated for authorized sharing group use. An attacker could craft a request with distribution set to 4 and an arbitrary sharing_group_id, potentially disclosing the existence or name of otherwise non-visible sharing groups and improperly modifying the distribution metadata of objects or contained attributes.

CVE-2026-54358 (GCVE-0-2026-54358)

Vulnerability from – Published: 2026-06-12 19:34 – Updated: 2026-06-15 13:02

Title
MISP organization administrators can target site administrator accounts for password reset
Summary
An incorrect authorization vulnerability in MISP allows an organization administrator to target site administrator accounts belonging to the same organization through the administrative email functionality. The affected code restricted organization administrators to users within their own organization, but did not exclude accounts assigned a site administrator role from recipient queries. As a result, an organization administrator could perform privileged account-management actions, such as initiating a password reset workflow, against a higher-privileged site administrator account in the same organization. Successful exploitation may allow an authenticated organization administrator to interfere with or potentially take over a site administrator account, resulting in privilege escalation and full compromise of the MISP instance’s confidentiality, integrity, and availability. Attack prerequisites: The attacker must be authenticated as an organization administrator in the same organization as a site administrator account.

CVE-2026-54357 (GCVE-0-2026-54357)

Vulnerability from – Published: 2026-06-12 19:25 – Updated: 2026-06-12 20:05

Title
MISP improper authorization allows organization administrators to modify site administrator user settings
Summary
An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration. The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.

CVE-2026-10860 (GCVE-0-2026-10860)

Vulnerability from – Published: 2026-06-04 13:34 – Updated: 2026-06-11 13:24
VLAI
Title
MISP CRUDComponent delete validation bypass via operator precedence error
Summary
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.

CVE-2026-10868 (GCVE-0-2026-10868)

Title
MISP user edit endpoint mass assignment vulnerability allows unauthorized user account modification
Summary
A mass assignment vulnerability exists in the MISP user edit functionality due to insufficient filtering of user-supplied fields in UsersController::edit(). When processing edit requests, the application accepted a user-controlled User.id value from request data. An authenticated attacker could craft a modified request containing another user identifier, potentially causing updates to be applied to an unintended user account. Depending on the editable fields and the attacker’s privileges, this could allow unauthorized modification of user account attributes and impact account integrity. The issue was addressed by explicitly removing the User.id field from request data before processing the user edit operation.
