Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the CDN plugin endpoints `plugin/CDN/status.json.php` and `plugin/CDN/disable.json.php` use key-based authentication with an empty string default key. When the CDN plugin is enabled but the key has not been configured (the default state), the key validation check is completely bypassed, allowing any unauthenticated attacker to modify the full CDN configuration — including CDN URLs, storage credentials, and the authentication key itself — via mass-assignment through the `par` request parameter. Commit adeff0a31ba04a56f411eef256139fd7ed7d4310 contains a patch.
