Description

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. Version affected: ≤2.5.45
