{"id":"CVE-2026-33650","aliases":["GHSA-8x77-f38v-4m5j"],"url":"https://o3.security/vulnerability/CVE-2026-33650","summary":"AVideo's Video Moderator Privilege Escalation via Ownership Transfer Enables Arbitrary Video Deletion","details":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, a user with the \"Videos Moderator\" permission can escalate privileges to perform full video management operations — including ownership transfer and deletion of any video — despite the permission being documented as only allowing video publicity changes (Active, Inactive, Unlisted). The root cause is that `Permissions::canModerateVideos()` is used as an authorization gate for full video editing in `videoAddNew.json.php`, while `videoDelete.json.php` only checks ownership, creating an asymmetric authorization boundary exploitable via a two-step ownership-transfer-then-delete chain. Commit 838e16818c793779406ecbf34ebaeba9830e33f8 contains a patch.","published":"2026-03-23T18:28:13.324Z","modified":"2026-08-12T03:51:11.249335349Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/838e16818c793779406ecbf34ebaeba9830e33f8","label":"WWBN/AVideo@838e168"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33650.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-8x77-f38v-4m5j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33650"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/838e16818c793779406ecbf34ebaeba9830e33f8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.249335349Z"}}
