# mcp-ffmpeg: crafted file paths let attackers run shell commands

mcp-ffmpeg through 1.0.5 passes videoPath and outputDir values into a shell command string via child_process.exec in the resize-video, extract-audio and get-video-info tools. An attacker who controls a file or directory name can embed $(), backticks or a double quote to run commands as the MCP server user.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed mcp-ffmpeg version, for example with `npm ls mcp-ffmpeg`, and see whether it is `1.0.5` or earlier.
- Look for the mcp-ffmpeg server in your MCP client configuration and confirm which tools it exposes.

## Fix

- Upgrade mcp-ffmpeg to a version later than `1.0.5`; the sources do not name the fixed release, so check the package registry.
- Until patched, stop exposing the resize-video, extract-audio and get-video-info tools to untrusted input and avoid running the server on directories that untrusted users can name.

## From the sources

mcp-ffmpeg through 1.0.5 contains an OS command injection vulnerability that allows attackers to run shell commands by supplying crafted videoPath or outputDir values to the resize-video, extract-audio and get-video-info tools. Attackers can embed $(), backticks or a closing double quote in an existing file or directory name to break out of the child_process.exec command string and execute commands as the MCP server user.
