CVE-2026-90543 Details
Description
WWBN AVideo at commit c3edcc274c389816d434acadac07ee78eaf330c1 and earlier, with the Live plugin enabled, contains a missing authentication vulnerability in plugin/Live/socketMessageLiveOwner.json.php. The script reads the `key` and `msg` parameters from $_REQUEST, resolves the stream owner via LiveTransmition::keyExists, and verifies that the stream owner (not the caller) is an administrator; it performs no User::isLogged() check and enforces no CSRF token. As a result, an unauthenticated remote attacker who knows an administrator's Live stream key can call sendSocketSuccessMessageToUsers_id and deliver arbitrary in-app/socket notification messages to that administrator. The issue was unpatched at the time of publication.
A missing authentication vulnerability has been identified in WWBN AVideo versions through commit c3edcc274c389816d434acadac07ee78eaf330c1, specifically within the Live plugin. The vulnerability resides in the 'plugin/Live/socketMessageLiveOwner.json.php' script, which fails to properly authenticate requests. The script reads the 'key' and 'msg' parameters from the request, checks the stream owner’s administrative status, but does not verify if the user is logged in or enforce a CSRF token. This allows an unauthenticated remote attacker who knows an administrator's Live stream key to send arbitrary in-app socket notifications to that administrator.
