{"id":"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.","aliases":["GHSA-v467-g7g7-hhfh"],"modified":"2026-04-10T05:42:39.754546Z","published":"2026-03-20T23:30:04.209Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33237.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"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":"FIX","url":"https://github.com/WWBN/AVideo/commit/df926e500580c2a1e3c70351f0c30f4e15c0fd83"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"aee1e11ee8d9343f87b7643e49cc32924b07979b"}]}],"versions":["10.8","11","11.1","11.1.1","11.5","11.6","12.4","14.3","14.3.1","18.0","2.2","2.7","21.0","22.0","24.0","25.0","3.4","4.0","7.2","7.3","7.4","7.6","7.7","7.8","8.1","8.5","8.6","8.7","8.9","8.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33237.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N"}]}
