Technical Analysis
WWBN AVideo through commit 9c39d8c8 contains an authorization bypass vulnerability. The function getToken() creates tokens that are not bound to any user identity or specific purpose. Additionally, the plugin Gallery endpoint (plugin/Gallery/view/sections.php) issues valid tokens to unauthenticated visitors. Attackers can exploit this by retrieving a token from the Gallery endpoint and then using it to bypass authorization checks in other subsystems such as view/hls.php, thereby gaining unauthorized access to restricted video content.
Potential Impact
An attacker can bypass authorization controls without any privileges or user interaction, gaining access to restricted video content. This exposure of sensitive information could lead to unauthorized viewing or distribution of protected media.
