CVE-2026-63305

AVideo through 29.0 contains an OS command injection vulnerability in the ffmpeg.json.php endpoint where notifyCode and callback parameters are concatenated into a shell command without escaping. Attackers who can craft a valid encrypted payload can inject arbitrary shell metacharacters into these fields to execute OS commands as the web-server user.

Summary		(es) AVideo hasta la versión 29.0 contiene una vulnerabilidad de inyección de comandos del sistema operativo (OS) en el endpoint ffmpeg.json.php donde los parámetros notifyCode y callback se concatenan en un comando de shell sin escape. Atacantes que pueden crear una carga útil cifrada válida pueden inyectar metacaracteres de shell arbitrarios en estos campos para ejecutar comandos del sistema operativo (OS) como el usuario del servidor web.
