CyberRota Analysis
AI-GeneratedAuthenticated users of LiteLLM prior to versions 1.88.6 and 1.96.2 are vulnerable to a flaw that allows them to redirect outbound API calls to a destination they control, potentially exposing sensitive provider credentials and other secrets. The inadequate validation of request parameters could lead to unauthorized access to internal services via server-side requests. Organizations utilizing LiteLLM should prioritize upgrading to the patched versions to mitigate the risk of credential leakage and unauthorized access.

Original NVD Description
LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to versions 1.88.6 and 1.96.2, any authenticated LiteLLM proxy user could redirect an outbound provider call to a destination the user controls and cause the proxy to send its configured provider credentials to that destination. Request validation in litellm/proxy/auth/auth_utils.py, litellm/proxy/common_request_processing.py, litellm/proxy/health_endpoints/_health_endpoints.py, litellm/proxy/image_endpoints/endpoints.py, and litellm/proxy/litellm_pre_call_utils.py used incomplete checks that did not cover every sensitive parameter or inspect equivalent values across nested request fields, path values, and bracket-notation form data. Routing and credential parameters including api_base, base_url, model_list, fallbacks, and litellm_credential_name could therefore be applied without clearing the operator's stored key, exposing upstream provider credentials and other configured secrets and permitting server-side requests to internal services reachable by the proxy. This issue is fixed in versions 1.88.6 and 1.96.2.
