Title
MISP Privilege Escalation: Read-Only API Key User Can Regain Full Role via updateLoginTime
Summary
MISP has a security issue that can let a user gain more access than their API key is supposed to allow.
A read-only API key should only let someone view information. However, after logging in with such a key, a specific MISP function could accidentally restore the user’s normal account permissions. This means someone with a read-only API key could potentially gain write, delete, or even administrator access if their underlying account has those permissions.
Exploiting the issue requires a valid read-only API key and a single request to the affected function.
The main impact is that MISP’s API key restrictions can be bypassed, allowing actions that the API key was specifically meant to prevent.

fix: [security] read only api keys can regain full role | d4143841f5f0… |
Fix summary
The fix removes the call to User::getAuthUser() and Auth::login() from the updateLoginTime() method, which was re-authenticating the user with their full role permissions. It replaces this with a call to _refreshAuth(), which refreshes the authentication state while preserving the current (restricted) permission level associated with the API key, preventing privilege escalation.
Patch summary
In app/Controller/UsersController.php, the updateLoginTime() method is modified: the lines that fetched the user record via User::find(), called User::getAuthUser() to retrieve the full auth user, and called Auth::login() to re-establish the session are removed. These are replaced with a single call to $this->_refreshAuth(), which updates the authentication context without upgrading the permission scope. Net change: 1 insertion, 6 deletions.
CVSS rationale
AV:N - the endpoint is accessible over the network via HTTP POST. AC:L - the attack requires only a single POST request to a known endpoint; no race conditions or complex timing. AT:N - no manipulation of the target system is needed beyond the API call. PR:L - the attacker must possess a valid read-only API key (authenticated user). UI:N - no user interaction is required. VC:H - the escalated user can read all data in the MISP instance that their full role permits. VI:H - the escalated user can create, modify, and delete threat intelligence data. VA:H - the escalated user can delete data, modify configurations, or disrupt the MISP service. SC/SI/SA:N - the impact is confined to the MISP instance itself; no cascading impact on other systems is evidenced.
Weakness rationale
- CWE-269 The system fails to maintain the restricted privilege level (read-only) associated with the API key authentication. The updateLoginTime endpoint re-establishes the session with the user's full role permissions, effectively granting higher privileges than the authentication credential intended. This is a failure to properly manage and enforce the privilege boundary during session refresh.
Attack pattern rationale
- CAPEC-114 The vulnerability arises because the updateLoginTime endpoint incorrectly reconfigures the user's privilege level during session refresh, upgrading from the API-key-scoped read-only permissions to the user's full role. The attacker exploits this misconfiguration by simply calling the endpoint. CAPEC-114 is the closest match as it covers scenarios where an application incorrectly assigns or maintains privilege levels. Uncertainty: no CAPEC specifically covers 'session privilege escalation via auth refresh,' so this is the best available approximation.
Assumptions to verify
- The tag_version_boundary indicates the fix commit is 141 commits before v2.5.47, implying v2.5.47 contains the fix; versions prior to v2.5.47 are assumed affected. No explicit version range is stated in the patch.
- The _refreshAuth() method is assumed to preserve the current API-key-scoped permission level rather than re-fetching full role permissions; this is inferred from the commit subject and the removal of getAuthUser()/Auth::login().
- The 'full role' referenced in the commit subject is assumed to be a higher-privilege role (e.g., admin or site admin) compared to the read-only API key scope.
- CAPEC-114 is the closest available attack pattern; no CAPEC specifically models session privilege escalation via authentication refresh, so this mapping carries some uncertainty.
- CVSS impact metrics (VC/VI/VA) assume the user's full role grants broad administrative access to the MISP instance; actual impact depends on the specific role assigned to the user.

Title
vm2 before 3.11.7 Denylist Bypass via fs/promises
Summary
vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries (e.g. require: { builtin: ['*', '-fs', '-child_process'] }), negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the builtin named fs and does not remove builtin subpaths such as fs/promises. Sandboxed code can therefore call require('fs/promises') or require('node:fs/promises') and reach the promise-based filesystem API despite fs being denied; node: prefix handling is likewise inconsistent (a -node:fs/promises entry does not block require('fs/promises')). Host file creation and writing were confirmed via fsp.writeFile(), and other fs/promises operations (cp, mkdir, rename, rm, rmdir, truncate, read operations, etc.) are also reachable. This issue is fixed in vm2 3.11.7.

Title
vm2 before 3.11.7 Authentication Bypass via node: Prefix
Summary
vm2 through 3.11.6 does not normalize `node:`-prefixed builtin specifiers when evaluating user-supplied negative (deny) entries in a NodeVM wildcard require policy. Although NodeVM strips the `node:` prefix during require() resolution, negative wildcard entries are matched by exact string comparison against the canonical builtin names, so a policy such as `new NodeVM({ require: { builtin: ['*', '-node:child_process'] } })` fails to deny the canonical `child_process` module. Sandboxed code can therefore obtain the host `child_process` builtin via `require('child_process')` or `require('node:child_process')`, gaining references to process-spawning APIs such as execSync and spawn, which is equivalent to host command-execution capability for untrusted sandbox code. Fixed in vm2 3.11.7. (Suggested title: "vm2 before 3.11.7: NodeVM builtin deny-list bypass via node:-prefixed specifiers exposes child_process")

Title
Booking Calendar <= 11.8.2 - Authenticated (Editor+) Privilege Escalation to 'data_name' Parameter
Summary
The Booking Calendar plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 11.8.2 via the `wpbc_ajax_option_save` AJAX action. The vulnerability exists because the `handle_ajax_save()` function applies per-option safeguards only to names explicitly registered via `register_option_policy()`, causing `get_option_policy()` to return an empty policy — bypassing all can_save, force_mode, and allowed_keys checks — for any unregistered option name, including core WordPress options, while an attacker-controlled `data_name` parameter passes through `sanitize_key()` and is written directly to `update_option()` without restriction. This makes it possible for authenticated attackers with Editor-level access and above to escalate their privileges to Administrator by writing core WordPress options such as `default_role=administrator` and `users_can_register=1`, then self-registering a new Administrator account. The nonce check does not meaningfully restrict this attack, as both the nonce value and nonce action are attacker-supplied POST parameters, and a valid nonce is trivially obtainable via `admin-ajax.php?action=rest-nonce`.

Title
Parallels Desktop local privilege escalation via appliance extract argument injection
Summary
Parallels Desktop runs prl_disp_service as root. Local clients reach it on the world-writable socket /var/run/prl_disp_service.socket. PrlSrv_LoginLocal accepts peer credentials. No Parallels signature. No admin group.
After login, PrlSrv_InstallAppliance lets you pick the appliance folder (sVmParentPath). The daemon unpacks with one string, tar -xf "%1" -C "%2", then Qt QProcess::splitCommand chops that string into words. A quote in the folder name closes early. The leftover text becomes extra tar flags. macOS tar --use-compress-program= runs the named program as root.

Mitigation MIT-1
Architecture and Design
Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-48
Architecture and Design
Strategy: Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Mitigation MIT-49
Architecture and Design
Strategy: Separation of Privilege
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
CAPEC-122: Privilege Abuse
An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
CAPEC-233: Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
CAPEC-58: Restful Privilege Elevation
An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
