CVE-2025-15691
The WPFunnels WordPress plugin before 3.13.0 does not check whether user registration is enabled on the site before creating accounts from opt-in form submissions, relying on a value supplied in the request instead, allowing unauthenticated attackers to create WordPress user accounts even when registration is disabled. This is an incomplete fix for CVE-2025-12353: the check added in 3.6.3 covers only one of the three registration paths.
