SCA: security update for github.com/open-policy-agent/opa (GHSA-f524-rf33-2jjr)

critical Tenable Cloud Security Plugin ID 414268

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 as such rejected — 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), isn’t 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. (CVE-2022-36085)
