Remediations

• The default configuration of the OIDC.Token entity is to restrict read/write access only to the administrator role. If this setting is not restrictive enough the option arises to change the access rule of the specific entity, or to create a different user role to handle different administrative tasks
• Currently no fix is available
• Update to V3.3.1 or later version
