Advisory details

Impact

LiteLLM Skills archive extraction did not sufficiently validate file paths from uploaded skill ZIP archives. 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, could upload a crafted skill archive containing path traversal entries.

When the skill was processed for execution, those entries could be written outside the intended extraction/staging directory. This could allow arbitrary file write and may lead to code execution depending on deployment configuration and writable paths.

Patches

The issue is fixed in 1.83.7-stable.

LiteLLM recommens upgrading to 1.83.7-stable or later.

Workarounds

If upgrading is not immediately possible:

  1. Block POST /v1/skills at your reverse proxy or API gateway.
  2. Restrict Skills API access to trusted users only.
