Detailsinfo

A vulnerability was found in CIRCL MISP up to 2.5.45. It has been classified as problematic. Affected is the function _shouldLog of the component Authentication Failure Logging. The manipulation with an unknown input leads to a insufficient logging vulnerability. CWE is classifying the issue as CWE-778. When a security-critical event occurs, the product either does not record the event or omits important details about the event when logging it. This is going to have an impact on confidentiality. CVE summarizes:

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 only returned true when a Redis instance existed and no throttle key was present. Therefore, when Redis was unavailable, the function did not allow the log write at all, effectively silencing authentication-failure logging for the duration of the outage. Version affected: ≤2.5.45

The advisory is available at github.com. This vulnerability is traded as CVE-2026-92002 since 09/15/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
