Prior to 7.1.2, the legacy destroy_form action on AttachmentsController deletes UploadCache Store records based solely on a user-supplied form_id without verifying that the requesting user owns those records. An authenticated attacker who learns another user's pending-upload UUID can silently remove temporary file uploads before the victim submits their ticket or article. 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-2026-65828","source_modified_at":"2026-09-25T18:38:58.822Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"zammad","vendor":"zammad","versions":[{"version":"< 7.1.2","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.3,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00204,"percentile":0.09827,"score_date":"2026-10-23"},"published_at":"2026-09-25T17:28:13.159Z","modified_at":"2026-09-25T18:38:58.822Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-65828","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T18:38:58.822Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-65828","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-x4f3-367g-m93g","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/zammad/zammad/commit/3b755736fdbee8ff6ddf53661d6912d3d3028325","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":"no","technical_impact":"partial","assessed_at":"2026-09-25T18:38:49.403514Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-25T18:38:58.822Z","content_hash":"214c46d1bdea6bacb9f56e1d425662ae42062e49b00d051c0a70c1c6f78391c4"}}
