CVSS 4.0
6.9 mediumCVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:NCVE-2026-92003
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
