Detailsinfo

A vulnerability was found in WPFunnels Plugin up to 3.12.x. It has been classified as critical. Affected is an unknown part. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on integrity, and availability. CVE summarizes:

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.
