{"id":"CVE-2026-92002","summary":"MISP: Authentication failure logging suppressed during Redis unavailability","details":"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.\n\n\nHowever, User-\u003esetupRedis() 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.\n\nVersion affected: ≤2.5.45","modified":"2026-09-18T03:30:29.907485133Z","published":"2026-09-15T11:24:21.354Z","database_specific":{"cwe_ids":["CWE-778"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92002.json","cna_assigner":"CIRCL"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92002.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92002"},{"type":"FIX","url":"https://github.com/MISP/MISP/commit/a39b25d2f"},{"type":"PACKAGE","url":"https://github.com/MISP/MISP"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/misp/misp","events":[{"introduced":"0"},{"fixed":"a39b25d2f"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.5.46"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92002.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
