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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/zammad/zammad/commit/3b755736fdbee8ff6ddf53661d6912d3d3028325","tags":[]},{"url":"https://github.com/zammad/zammad/security/advisories/GHSA-x4f3-367g-m93g","tags":[]}],"exploitRefs":[{"url":"https://github.com/zammad/zammad/commit/3b755736fdbee8ff6ddf53661d6912d3d3028325","tags":[]},{"url":"https://github.com/zammad/zammad/security/advisories/GHSA-x4f3-367g-m93g","tags":[]}],"hasPoc":true,"ai":null}
