{"id":"CVE-2026-33293","aliases":["GHSA-xmjm-86qv-g226"],"url":"https://o3.security/vulnerability/CVE-2026-33293","summary":"AVideo Affected by Arbitrary File Deletion via Path Traversal in CloneSite deleteDump Parameter","details":"WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.","published":"2026-03-22T16:35:16.181Z","modified":"2026-08-12T03:51:44.544169602Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/941decd6d19e2e694acb75e86317d10fbb560284","label":"WWBN/AVideo@941decd"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33293.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-xmjm-86qv-g226"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33293"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/941decd6d19e2e694acb75e86317d10fbb560284"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.544169602Z"}}
