A flaw was found in LiteLLM. A database query used for proxy API key checks incorrectly incorporated caller-supplied key values directly into the query. This vulnerability allows an unauthenticated attacker to send a specially crafted Authorization header to any Large Language Model (LLM) API route, exploiting the proxy's error-handling path. Successful exploitation could enable the attacker to read and potentially modify data within the proxy's database, leading to unauthorized access to the proxy and its managed credentials.
