AnalysisAIv1 – Sep 16, 2026

Failed authentication attempts against MISP 2.5.45 and earlier stop being written to the audit log whenever the Redis instance used for log throttling is unreachable, and they remain unwritten for the entire duration of the outage. The flaw is in AppController::_shouldLog(), which treats 'Redis returned false' as 'nothing to log' rather than degrading to verbose logging, so brute-force or credential-stuffing activity against the login endpoint silently disappears from the record. No public exploit code and no CISA KEV entry exist for this issue, and the vendor shipped a fix in MISP 2.5.46 via commit a39b25d2f.

DescriptionCVE.org

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.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
