{"schema":"threatline.record/2","record":{"id":"CVE-2026-84461","aliases":["GHSA-6vh5-pfp2-5rmh"],"summary":"Zammad: Missing rate limiting allows password brute-forcing during two-factor login","details":"Zammad is a web based open source helpdesk/customer support system. 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.","categories":["Applications & CMS"],"product":"zammad","vendor":"zammad","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84461","source_modified_at":"2026-09-25T18:41:14.822Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"zammad","vendor":"zammad","versions":[{"status":"affected","version":"< 7.1.2"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/zammad/zammad/security/advisories/GHSA-6vh5-pfp2-5rmh","source_modified_at":"2026-09-02T21:20:10Z","fetched_at":"2026-10-23T21:47:51.402276Z","package":{"ecosystem":"","name":"Zammad"},"range":"<= 7.1.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/zammad/zammad/security/advisories/GHSA-6vh5-pfp2-5rmh","source_modified_at":"2026-09-02T21:20:10Z","fetched_at":"2026-10-23T21:47:51.402276Z","package":{"ecosystem":"","name":"Zammad"},"version":"7.1.2"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00324,"percentile":0.24276,"score_date":"2026-10-23"},"published_at":"2026-09-25T18:21:20.015Z","modified_at":"2026-09-25T18:41:14.822Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-84461","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T18:41:14.822Z"},{"source":"GitHub Advisory Database","url":"https://github.com/zammad/zammad/security/advisories/GHSA-6vh5-pfp2-5rmh","fetched_at":"2026-10-23T21:47:51.402276Z","source_modified_at":"2026-09-02T21:20:10Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-84461","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/zammad/zammad/security/advisories/GHSA-6vh5-pfp2-5rmh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/zammad/zammad/commit/d51254f1c6da13f6ee27636a5c82e53f7e59666b","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-25T18:41:07.364423Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-25T18:41:14.822Z","content_hash":"9304d5d6725d88fb56895e1e40403917f08c2b9f362c22d19909bb6f2da3b38f"}}
