Prior to 7.1.2, attacker-controlled HTML in inbound emails or tickets could bypass the image URL sanitizer using path traversal sequences. When an authenticated agent views the content, the browser resolves the URL to a protected API endpoint and sends the request with the agent's session cookie, enabling side effects such as forced logout without any user interaction. 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-2026-63006","source_modified_at":"2026-09-29T18:03:56.994Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"zammad","vendor":"zammad","versions":[{"version":"< 7.1.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0048,"percentile":0.40508,"score_date":"2026-10-23"},"published_at":"2026-09-25T18:23:13.578Z","modified_at":"2026-09-29T18:03:56.994Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-63006","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T18:03:56.994Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-63006","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/zammad/zammad/security/advisories/GHSA-33p2-cm7w-62g3","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/zammad/zammad/commit/856af85c12413087d6a74ffee25b16048a5ed8c3","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":"2026-09-29T18:03:28.018447Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-29T18:03:56.994Z","content_hash":"3fb0dddd2bceb0cc8b10eb9cd9ff17ec5ef794e03a7f1977244b4e0e80fc6daa"}}
