Doc Text:	A flaw was found in LiteLLM, a proxy server for Large Language Model (LLM) APIs. An authenticated user, with specific API route access, could upload a specially crafted skill archive. This archive, containing path traversal entries, would allow files to be written outside of the designated extraction directory. This vulnerability could lead to arbitrary file creation or modification, potentially resulting in system compromise.	Story Points:	---

Description OSIDB Bzimport 2026-07-08 20:01:48 UTC

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.83.7-stable, LiteLLM Skills archive extraction did not sufficiently validate file paths from uploaded skill ZIP archives, allowing an authenticated user with access to LiteLLM LLM API routes or a key whose allowed_routes includes /v1/skills, anthropic_routes, or llm_api_routes to upload a crafted skill archive containing path traversal entries that could be written outside the intended extraction or staging directory. This issue is fixed in version 1.83.7-stable.
