CVE-2026-92002: Insufficient Logging

Affected versions of MISP use Redis to throttle repeated authentication-failure log entries. The intent is to avoid excessive duplicate logs while still recording failed authentication activity. However, User-setupRedis returns false when Redis cannot be reached. The vulnerable shouldLog logic on...

CVE-2026-92003: Allocation of Resources Without Limits or Throttling

Affected versions of MISP do not consistently apply the existing authentication-failure logging throttle. Two API authentication failure branches wrote directly to the Log model: - API requests with no authentication key; - requests supplying an API key with an incorrect length Unlike other...

CVE-2026-91846: Missing Authorization

Affected versions of MISP allow a collection element to be created from a bare UUID without consistently checking whether the acting user is allowed to access the referenced object. The commit explains that collection elements themselves only store UUIDs, while the collection view later resolves...

PT-2026-91907

Affected versions of MISP expose several state-changing controller actions without restricting them to POST. The affected actions are: - EventReportsController::purgeUnusedPictures - NoticelistsController::enableNoticelist - ServersController::removeOrphanedCorrelations -...

PT-2026-91908

Affected versions of MISP can record incorrect access-log data for requests that terminate in an exception. Because CakeErrorController extends AppController, exception rendering runs the application startup path a second time. As a result, accessMonitor calls AccessLog::logRequest twice for one...

PT-2026-91905

Affected versions of MISP incorrectly filter dashboard templates that are restricted to a specific permission flag. DashboardsController::listTemplates allowed a template when either: - its restrict to permission flag matched one of the current user’s permission flags, or - restrict to permission...

PT-2026-91897

Affected versions of MISP fail to authorize a submitted sharing group in a specific event-edit path. The vulnerable logic checked whether the acting user could use a sharing group id only when the request explicitly supplied distribution = 4. If the attacker instead omitted distribution but...

CVE-2026-91825: Missing Authorization

Affected versions of MISP fail to authorize a submitted sharing group in a specific event-edit path. The vulnerable logic checked whether the acting user could use a sharinggroupid only when the request explicitly supplied distribution = 4. If the attacker instead omitted distribution but supplie...

CVE-2026-90961

The LdapAuth and LinOTPAuth authentication plugins in MISP contain an authentication bypass vulnerability. Both LdapAuthenticate and LinOTPAuthenticate replace CakePHP's FormAuthenticate class but fail to replicate its checkFields input validation guard. As a result, the email and password fields...

CVE-2026-90961 MISP LdapAuth and LinOTPAuth Authentication Bypass via Empty or Non-String Credentials

The LdapAuth and LinOTPAuth authentication plugins in MISP contain an authentication bypass vulnerability. Both LdapAuthenticate and LinOTPAuthenticate replace CakePHP's FormAuthenticate class but fail to replicate its checkFields input validation guard. As a result, the email and password fields...

CVE-2026-90961

MISP ≤2.5.45 contains an authentication bypass in the LdapAuth and LinOTPAuth plugins. Both replace CakePHP's FormAuthenticate but omit its _checkFields() validation guard, allowing empty or non-string credentials to reach downstream logic. In the LDAP authenticator, an empty password forwarded t...

CVE-2026-90955

Affected versions of MISP’s interactive CLI shell do not reliably preserve the identity of the impersonated MISP user across audit logging. The shell is designed to run actions as a supplied MISP user ID. However, the legacy SysLogLogable behavior stored that identity in behavior-instance state...

CVE-2026-90957

Affected versions of MISP serve uploaded SVG images inline without a restrictive browser sandbox. The commit explains that SVG files are XML documents rather than passive bitmap images. While scripts inside SVG do not execute when the SVG is rendered through a normal , they can execute when the S...
