CVE-2026-92003

MEDIUMPre-NVD 6.96.9
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 62% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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
