LiteLLM: SQL injection in Proxy API key verification

Published May 8, 2026 · Updated Jul 15, 2026 · Assigned by GitHub_M

Vendor: BerriAI Product: litellm Package: airflow-3 Package: litellm Ecosystem: PyPI Ecosystem: Wolfi

Description

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From version 1.81.16 to before version 1.83.7, a database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorised access to the proxy and the credentials it manages. This issue has been patched in version 1.83.7.
