What is CVE-2026-111579?

The Forminator Forms plugin for WordPress, prior to version 1.58.4, has a critical flaw in its handling of payment requirements. When a configured payment gateway becomes unavailable, the plugin fails to enforce payment on the server side. This allows unauthenticated users to bypass payment requirements for User Registration forms, gaining access to roles assigned to these forms, including potentially elevated privileges such as administrator. This vulnerability poses a significant risk as it enables unauthorized access to critical functionalities within the WordPress site.

Affected Version(s)

Forminator Forms 1.58.0 < 1.58.4

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
