Vulnerability Title
LiteLLM: SQL injection in Proxy API key verification
Source: NVD (National Vulnerability Database)
Vulnerability 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.

Vulnerability Title
LiteLLM SQL注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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 1.81.16版本至1.83.7之前版本存在SQL注入漏洞，该漏洞源于代理API密钥检查期间使用的数据库查询将调用者提供的密钥值混合到查询文本中而非作为单独参数传递，可能导致未经身份验证的攻击者发送特制授权标头到任何LLM API路由，通过代理的错误处理路径读取数据库数据并可能修改数据，导致未经授权访问代理及其管理的凭据。
