Patches

The problem has been patched in all affected versions. Please see the list of patched versions for the most appropiate one for your individual case.

Workarounds

Users who do not wish or are not able to upgrade can add an authentication configuration containing ClaimsValidator, which throws an exception if Claims are Skill Claims.
