MISP Unthrottled Authentication Failure Log Writes Enable Resource Exhaustion
cve-program · CVE-2026-92003
PublishedAffected 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

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
