CyberRota Analysis

AI-Generated

LiteLLM versions prior to 1.83.7-stable are vulnerable to path traversal attacks due to inadequate validation of file paths in uploaded skill ZIP archives. This flaw allows authenticated users to upload malicious skill archives that can extract files outside the designated directories, potentially leading to unauthorized access or data exposure. Organizations using LiteLLM, particularly those with access to LLM API routes, should prioritize upgrading to the latest version to mitigate this risk.

Original NVD Description

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.
