The B Blocks plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization and improper input validation within the rgfr_registration() function in all versions up to, and including, 2.0.6. This makes it possible for unauthenticated attackers to create a new account and assign it the administrator role.
