Description
Video-stitch before 2.0.0-beta.1 contains an OS command injection vulnerability that allows attackers to execute commands by supplying file names interpolated unquoted into shell-executed ffmpeg command lines. Attackers who influence file names passed to concat(), cut(), or merge() can inject shell metacharacters to run commands with the Node.js process privileges.
