Vulnerability from github – Published: 2025-08-12 06:34 – Updated: 2025-08-12 06:34

Details

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.

Severity ?

9.8 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
