CVE-2026-85696Public exploitNetwork attack vector

Command execution via unescaped audio filename

Published Sep 4, 2026 · Updated Sep 4, 2026

OS command injection in OpenTalker SadTalker 0.0.2 and earlier allows remote attackers to run commands via an audio upload. The save_video_with_watermark function inserts the uploaded audio path into a double-quoted ffmpeg command string and passes it to os.system without escaping shell metacharacters. Exploitation requires access to a network-exposed Gradio interface and video generation; injected commands run with the SadTalker process's privileges.
