{"cve":"CVE-2026-33650","nvd":{"published":"2026-03-23T19:16:41.223","modified":"2026-06-17T10:37:51.897","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L","score":7.6},"cwes":["CWE-863"],"references":["https://github.com/WWBN/AVideo/commit/838e16818c793779406ecbf34ebaeba9830e33f8","https://github.com/WWBN/AVideo/security/advisories/GHSA-8x77-f38v-4m5j","https://github.com/WWBN/AVideo/security/advisories/GHSA-8x77-f38v-4m5j"],"products":["wwbn:avideo"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33650","score":0.00244,"percentile":0.15688,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
