Overview
chrome-devtools-mcp is a MCP server for Chrome DevTools
Affected versions of this package are vulnerable to Symlink Attack in the fs.writeFileSync process when writing the PID file to a runtime directory under /tmp if $XDG_RUNTIME_DIR is unset. An attacker can overwrite or truncate arbitrary files writable by the victim user by pre-creating a symlink at the expected PID file location. This is only exploitable if the victim is running on a POSIX system (macOS or Linux) with $XDG_RUNTIME_DIR unset and the attacker has a local user account on the same host.
