Authenticated arbitrary file write via FFmpeg arguments
Published Mar 7, 2026 · Updated Mar 7, 2026
Argument injection in FFmate 2.0.15 and earlier allows remote authenticated users to write arbitrary files through crafted presets. The Execute function parses each preset command into arguments and passes them directly to FFmpeg without restricting options or output paths. Low-privileged API access is required; writable targets can be overwritten with attacker-controlled content, including SSH keys.
