      "value": "WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `Live_schedule::keyExists()` method constructs a SQL query by interpolating a stream key directly into the query string without parameterization. This method is called as a fallback from `LiveTransmition::keyExists()` when the initial parameterized lookup returns no results. Although the calling function correctly uses parameterized queries for its own lookup, the fallback path to `Live_schedule::keyExists()` undoes this protection entirely. This vulnerability is distinct from GHSA-pvw4-p2jm-chjm, which covers SQL injection via the `live_schedule_id` parameter in the reminder function. This finding targets the stream key lookup path used during RTMP publish authentication. As of time of publication, no patched versions are available."

      "value": "WWBN AVideo es una plataforma de video de código abierto. En versiones hasta la 26.0 inclusive, el método ’Live_schedule::keyExists()’ construye una consulta SQL interpolando una clave de transmisión directamente en la cadena de consulta sin parametrización. Este método es llamado como un mecanismo de respaldo desde ’LiveTransmition::keyExists()’ cuando la búsqueda parametrizada inicial no devuelve resultados. Aunque la función que llama utiliza correctamente consultas parametrizadas para su propia búsqueda, la ruta de respaldo a ’Live_schedule::keyExists()’ deshace esta protección por completo. Esta vulnerabilidad es distinta de GHSA-pvw4-p2jm-chjm, que cubre la inyección SQL a través del parámetro ’live_schedule_id’ en la función de recordatorio. Este hallazgo se dirige a la ruta de búsqueda de la clave de transmisión utilizada durante la autenticación de publicación RTMP. Al momento de la publicación, no hay versiones parcheadas disponibles."
