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.","state":0,"publishedAt":"2026-09-25T18:23:13.578+00:00","modifiedAt":"2026-09-29T18:03:56.994+00:00","affected":[{"ecosystem":"Vendor product","name":"zammad","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"zammad\",\n                    \"product\": \"zammad\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.1.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/zammad/zammad/security/advisories/GHSA-33p2-cm7w-62g3","https://github.com/zammad/zammad/commit/856af85c12413087d6a74ffee25b16048a5ed8c3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-63006","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63006","identifiers":["CVE-2026-63006"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
