medium Tenable Cloud Security Plugin ID 458980

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-59820)

Solution

Update the litellm library and its related packages to version 1.83.7 or later.
