{"id":"CVE-2026-33351","aliases":["GHSA-5f7v-4f6g-74rj"],"url":"https://o3.security/vulnerability/CVE-2026-33351","summary":"AVideo has Unauthenticated SSRF via `webSiteRootURL` Parameter in saveDVR.json.php, Chaining to Verification Bypass","details":"WWBN AVideo is an open source video platform. Prior to version 26.0, a Server-Side Request Forgery (SSRF) vulnerability exists in `plugin/Live/standAloneFiles/saveDVR.json.php`. When the AVideo Live plugin is deployed in standalone mode (the intended configuration for this file), the `$_REQUEST['webSiteRootURL']` parameter is used directly to construct a URL that is fetched server-side via `file_get_contents()`. No authentication, origin validation, or URL allowlisting is performed. Version 26.0 contains a patch for the issue.","published":"2026-03-23T13:51:43.972Z","modified":"2026-08-12T03:51:14.889291289Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/d0c54960389eeb85e76caed5a257ae90e6a739f2","label":"WWBN/AVideo@d0c5496"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33351.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-5f7v-4f6g-74rj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33351"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/d0c54960389eeb85e76caed5a257ae90e6a739f2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:14.889291289Z"}}
