CVE-2026-49279

WWBN AVideo is an open source video platform. Versions 29.0 and below contain a Stored XSS vulnerability through the autoEvalCodeOnHTML parameter in the MessageSQLite WebSocket Handler. The MessageSQLite.php handler only strips autoEvalCodeOnHTML from $json['msg'], but msgToResourceId() reads from $msg['json'] with higher priority. An attacker can place the XSS payload in the json key instead of msg, bypassing the sanitization entirely. An authenticated attacker can execute arbitrary JavaScript
