Description

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the endpoint `plugin/Permissions/View/Users_groups_permissions/list.json.php` lacks any authentication or authorization check, allowing unauthenticated users to retrieve the complete permission matrix mapping user groups to plugins. All sibling endpoints in the same directory (`add.json.php`, `delete.json.php`, `index.php`) properly require `User::isAdmin()`, indicating this is an oversight. Commits dc3c825734628bb32550d0daa125f05bacb6829c and b583acdc9a9d1eab461543caa363e1a104fb4516 contain patches.
