Detailsinfo

A vulnerability classified as critical has been found in WWBN AVideo (version unknown). This affects the function sendSocketSuccessMessageToUsers_id of the file plugin/Live/socketMessageLiveOwner.json.php of the component Live plugin. The manipulation of the argument key/msg with an unknown input leads to a missing authentication vulnerability. CWE is classifying the issue as CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. This is going to have an impact on integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-90543 since 09/12/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
