{"id":"CVE-2026-33237","aliases":["GHSA-v467-g7g7-hhfh"],"url":"https://o3.security/vulnerability/CVE-2026-33237","summary":"AVideo has SSRF in Scheduler Plugin via callbackURL Missing `isSSRFSafeURL()` Validation","details":"WWBN AVideo is an open source video platform. Prior to version 26.0, the Scheduler plugin's `run()` function in `plugin/Scheduler/Scheduler.php` calls `url_get_contents()` with an admin-configurable `callbackURL` that is validated only by `isValidURL()` (URL format check). Unlike other AVideo endpoints that were recently patched for SSRF (GHSA-9x67-f2v7-63rw, GHSA-h39h-7cvg-q7j6), the Scheduler's callback URL is never passed through `isSSRFSafeURL()`, which blocks requests to RFC-1918 private addresses, loopback, and cloud metadata endpoints. An admin can configure a scheduled task with an internal network `callbackURL` to perform SSRF against cloud infrastructure metadata services or internal APIs not otherwise reachable from the internet. Version 26.0 contains a patch for the issue.","published":"2026-03-20T23:30:04.209Z","modified":"2026-08-07T11:48:53.895918847Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":"26.0"}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/df926e500580c2a1e3c70351f0c30f4e15c0fd83","label":"WWBN/AVideo@df926e5"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33237.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-v467-g7g7-hhfh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33237"},{"type":"REPORT","url":"https://github.com/WWBN/AVideo/issues/10403"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/df926e500580c2a1e3c70351f0c30f4e15c0fd83"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:53.895918847Z"}}
