### 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.
