CVE-2026-33351 (opens in a new tab)How to fix?
Upgrade wwbn/avideo to version 29.0 or higher.
Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the webSiteRootURL parameter in the saveDVR.json.php endpoint. An attacker can cause the server to make arbitrary HTTP requests to internal or external resources, potentially accessing sensitive information or bypassing authentication by supplying a crafted URL. This can also allow the attacker to control the verification flow and manipulate downstream processing.
Note: This is only exploitable if the application is deployed in standalone mode and the configuration file is missing, allowing the fallback to the attacker-controlled parameter.
