| description: | |
| 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. |
| |
| A 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`. |
