CVE-2026-110649
Stills anterior a la versión 25.24.2 contiene una vulnerabilidad de inyección de comandos del sistema operativo que permite a los atacantes ejecutar comandos de shell mediante rutas de archivos multimedia manipuladas. Los atacantes pueden nombrar un archivo multimedia con $(...) o con comillas invertidas (backticks) para ejecutar comandos del sistema operativo con los privilegios del proceso de Node.js cuando se ejecutan ffmpeg, ffprobe, gifsicle o convert.
