# CVE-2026-92002

## Summary

- **CVE ID:** CVE-2026-92002
- **Severity:** MEDIUM
- **CVSS Score:** 5.1 (CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N)
- **CWE:** CWE-778
- **Published:** Sep 15, 2026
- **Last Modified:** Sep 15, 2026

## Description

Affected versions of MISP use Redis to throttle repeated authentication-failure log entries. The intent is to avoid excessive duplicate logs while still recording failed authentication activity.


However, User->setupRedis() returns false when Redis cannot be reached. The vulnerable _shouldLog() logic only returned true when a Redis instance existed and no throttle key was present. Therefore, when Redis was unavailable, the function did not allow the log write at all, effectively silencing authentication-failure logging for the duration of the outage.

Version affected: ≤2.5.45
