CVE-2026-46721Broken Access Control in extension "Frontend User Registration" (sf_register)

Updated under an hour ago ()

Does this affect you?

It affects TYPO3 Extension "Frontend User Registration". Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
