CVE-2026-92003

MISP Unthrottled Authentication Failure Log Writes Enable Resource Exhaustion

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 authentication failures, these paths bypassed _shouldLog(), so every request could create another durable auth_fail entry.
