Affected packages
• npm @backstage/plugin-permission-backend: < 0.6.0 → fixed in 0.6.0
Description
Impact
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.
Patches
This issue has been resolved in version `0.6.0` of the permissions backend.
Workarounds
Administrators of the permission policies can ensure that they are crafted in such a way that conditional decisions do not contain any sensitive information.
