Protection Mechanism Failure
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 by the compiler if encountered in the policy compilation stage. A bypass of this protection has been found, where the use of the with
keyword to mock such a built-in function (a feature introduced in OPA v0.40.0), is not taken into account by WithUnsafeBuiltins
. Multiple conditions need to be met in order to create an adverse effect. Version 0.43.1 contains a patch for this issue. As a workaround, avoid using the WithUnsafeBuiltins
function and use the capabilities
feature instead.
All versions starting from 0.40.0 before 0.43.1
Upgrade to version 0.43.1 or above.
