CVE-2025-32791 Details
Description
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.
A vulnerability exists in the Backstage permission plugin backend, specifically in versions prior to 0.6.0. This issue allows callers to access certain information about the conditional decisions made by the permission policy in use. The vulnerability only impacts systems where the permission policy utilizes conditional decisions; otherwise, there is no effect. Additionally, if the permission system is not active, there is no impact.
Users can upgrade to version 0.6.0 of the Backstage permission backend to address this vulnerability. Alternatively, permission policy administrators can ensure that their policies do not include sensitive information in conditional decisions.
