Description

The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to improper control of dynamically-managed code resources in the POST /guardrails/test_custom_code endpoint when running user-supplied Python inside a hand-rolled sandbox. A remote privileged user can submit crafted Python code to execute arbitrary code.

In default configurations, reaching the endpoint requires a proxy-admin credential. The proxy process runs as root in the default Docker image.
