Prior to 7.1.2, the two-factor login step let an attacker try unlimited password guesses for any account without triggering Zammad's normal lockout or rate limiting. The response also revealed whether a guess was correct, even before two-factor authentication was checked. This made it possible to brute-force weak or reused passwords. This issue is fixed in version 7.1.2.","evidence":"cve:CVE-2026-84461","products":[{"name":{"value":"zammad","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-84461","aliases":["CVE-2026-84461"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":6.9,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"LOW"}}],"affected":[{"vendor":"zammad","product":"zammad","versions":[{"status":"affected","version":"< 7.1.2"}]}],"modified":"2026-09-25T18:41:14.822Z","provider":"cve","references":["https://github.com/zammad/zammad/security/advisories/GHSA-6vh5-pfp2-5rmh","https://github.com/zammad/zammad/commit/d51254f1c6da13f6ee27636a5c82e53f7e59666b"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-84461","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-25T18:41:07.364423Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-25T18:41:14.822Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T18:21:20.015Z"}}},"related_cves":[{"value":"CVE-2026-84461","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":2239,"next_before":2239}
