WWBN AVideo is an open source video platform. In versions 29.0 and below, the allowOrigin($allowAll=true) function in objects/functions.php reflects any arbitrary Origin header back in Access-Control-Allow-Origin along with Access-Control-Allow-Credentials: true. This function is called by both plugin/API/get.json.php and plugin/API/set.json.php - the primary API endpoints that handle user data retrieval, authentication, livestream credentials, and state-changing operations. Combined with the application's SameSite=None session cookie policy, any website can make credentialed cross-origin requests and read authenticated API responses, enabling theft of user PII, livestream keys, and performing state changes on behalf of the victim. Commit caf705f38eae0ccfac4c3af1587781355d24495e contains a fix.
