Summary

mcp-ffmpeg through 1.0.5 contains OS command injection (CWE-78) in the resize-video, extract-audio and get-video-info tools. An attacker can embed $(), backticks or a closing double quote in an existing file or directory name supplied as videoPath or outputDir, breaking out of the child_process.exec command string. Injected commands run as the MCP server user. CVSS 4.0 scores the issue 7.3 (HIGH), and CISA has not added it to KEV.
