CVE-2026-33237
March 20, 2026
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.
