SCA: security update for @backstage/plugin-permission-backend (GHSA-f8j4-p5cr-p777)

medium Tenable Cloud Security Plugin ID 425697

Description

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

- The Backstage Scaffolder plugin houses types and utilities for building scaffolder-related modules. A
vulnerability in the Backstage permission plugin backend allows callers to extract some information about
the conditional decisions returned by the permission policy installed in the permission backend. If the
permission system is not in use or if the installed permission policy does not use conditional decisions,
there is no impact. This issue has been patched in version 0.6.0 of the permissions backend. A workaround
includes having administrators of the permission policies ensure that they are crafted in such a way that
conditional decisions do not contain any sensitive information. (CVE-2025-32791)
