Title
Broken Access Control in extension "Frontend User Registration" (sf_register)
Summary
The create and edit flows do not restrict which user properties may be submitted and do not enforce access control on the frontend user group assignment. As a result, an attacker can assign an arbitrary frontend user group to a newly registered or edited account, gaining unauthorized access to content and functionality restricted to privileged frontend user groups.
Severity ?
