CVE-2026-59821 PUBLISHED

LiteLLM: Custom Code Guardrails production endpoints bypass code safety checks

Assigner: GitHub_M
Reserved: 07.07.2026 Published: 08.07.2026 Updated: 09.07.2026

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.82.0-stable, LiteLLM's Custom Code Guardrails production create and update paths did not apply the same sandboxing and validation used by the test endpoint, allowing a privileged user with access to create or update guardrails to submit custom Python code that executed in the LiteLLM proxy environment and could expose secrets available to the process. This issue is fixed in version 1.82.0-stable.
