    Issue
    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.

    Recommended action: Upgrade to 0.6.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
