Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, the extractArchive and compressFiles endpoints in file-manager.ts use double-quoted strings for shell command construction, unlike all other file manager operations which use single-quote escaping. Double quotes allow $(command) substitution, enabling command injection on the remote SSH host. This issue has been patched in version 2.1.0.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
