Technical description
The CRM Memberships plugin for WordPress is vulnerable to unauthorized membership tag creation due to a missing capability check on the 'ntzcrm_add_new_tag' function in all versions up to, and including, 2.5. This makes it possible for unauthenticated attackers to create arbitrary membership tags and modify CRM configuration that should be restricted to administrators.
