CVE-2026-35029— LiteLLM affected by privilege escalation via unrestricted proxy configuration endpoint

LiteLLM affected by privilege escalation via unrestricted proxy configuration endpoint

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.83.0, the /config/update endpoint does not enforce admin role authorization. A user who is already authenticated into the platform can then use this endpoint to modify proxy configuration and environment variables, register custom pass-through endpoint handlers pointing to attacker-controlled Python code, achieving remote code execution, read arbitrary server files by setting UI_LOGO_PATH and fetching via /get_image, and take over other privileged accounts by overwriting UI_USERNAME and UI_PASSWORD environment variables. Fixed in v1.83.0.

N/A

授权机制不正确

LiteLLM 安全漏洞

LiteLLM是Berri AI开源的一个应用程序。可以使用 OpenAI 格式调用所有 LLM API。 LiteLLM 1.83.0之前版本存在安全漏洞，该漏洞源于/config/update端点未强制执行管理员角色授权，可能导致经过身份验证的用户修改代理配置和环境变量，实现远程代码执行。
