GHSA-72m8-9m7m-h278: LiteLLM: Custom Code Guardrails production endpoints bypass code safety checks

OSV AI package advisories · observation · Jul 22, 2026 · UTC

### 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 deployments without a configured master key, callers could be treated as proxy administrators, making this reachable without intended administrative authorization. This could allow arbitrary code execution in the LiteLLM proxy container and exposure of secrets available to the process. ### Patches The is
