GHSA-72M8-9M7M-H278 LiteLLM: Custom Code Guardrails production endpoints bypass code safety checks

Impact LiteLLM's Custom Code Guardrails production create/update paths did not apply the same sandboxing and validation used by the test endpoint. A privileged user with access to create or update guardrails could submit custom Python code that executed in the LiteLLM proxy environment. In...

LiteLLM: MCP Authentication Bypass via OAuth2 Passthrough Fallback

Impact LiteLLM's MCP Streamable HTTP endpoint could allow an unauthenticated attacker to establish an authenticated MCP session using an arbitrary Bearer token. The MCP auth handler supported OAuth2 passthrough for upstream MCP servers, but the fallback path could replace failed LiteLLM key...

GHSA-4G5M-C9R5-49XF LiteLLM: Local file read via request-supplied OIDC file references

Impact LiteLLM's /health/testconnection endpoint resolved request-supplied environment and OIDC file references in litellmparams. A proxy administrator, or another privileged caller with permission to test model connections, could cause LiteLLM to read files from the local filesystem via an...
