Official description

WWBN AVideo is an open source video platform. In versions up to and including 29.0, two endpoints (plugin/AI/receiveAsync.json.php and objects/EpgParser.php) in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections. Commit 603e7bf77a835584387327e35560262feb075db3 contains an updated fix.
