Summary
LiteLLM is a proxy server (a middleman that forwards requests to different AI services) that had a vulnerability before version 1.83.7-stable where it didn't properly check file paths when extracting uploaded skill files (packaged as ZIP archives). This meant an authenticated user could upload a specially crafted file that uses path traversal (a technique to write files outside the intended folder) to place files in dangerous locations on the server.
Solution / Mitigation
Update to version 1.83.7-stable or later.
