  "summary": "Protection bypass in github.com/open-policy-agent/opa",
  "details": "Open Policy Agent (OPA) is an open source, general-purpose policy engine. The Rego compiler provides a (deprecated) WithUnsafeBuiltins function, which allows users to provide a set of built-in functions that should be deemed unsafe and rejected by the compiler if encountered in the policy compilation stage.\n\nA bypass of this protection is possible when using the \"with\" keyword to mock a built-in function that isn't taken into account by WithUnsafeBuiltins.",
