SCA: security update for github.com/open-policy-agent/opa (GHSA-hcw3-j74m-qc58)

medium Tenable Cloud Security Plugin ID 415650

Description

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

- OPA is an open source, general-purpose policy engine. Under certain conditions, pretty-printing an
abstract syntax tree (AST) that contains synthetic nodes could change the logic of some statements by
reordering array literals. Example of policies impacted are those that parse and compare web paths. **All
of these** three conditions have to be met to create an adverse effect: 1. An AST of Rego had to be
**created programmatically** such that it ends up containing terms without a location (such as wildcard
variables). 2. The AST had to be **pretty-printed** using the `github.com/open-policy-agent/opa/format`
package. 3. The result of the pretty-printing had to be **parsed and evaluated again** via an OPA instance
using the bundles, or the Golang packages. If any of these three conditions are not met, you are not
affected. Notably, all three would be true if using **optimized bundles**, i.e. bundles created with `opa
build -O=1` or higher. In that case, the optimizer would fulfil condition (1.), the result of that would
be pretty-printed when writing the bundle to disk, fulfilling (2.). When the bundle was then used, we'd
satisfy (3.). As a workaround users may disable optimization when creating bundles. (CVE-2022-23628)
