What is CVE-2026-111597?

The Forminator Forms plugin for WordPress prior to version 1.58.4 contains a significant security flaw that fails to verify whether a Stripe Checkout payment has been successfully completed. This shortcoming enables unauthorized users to access post-payment redirect URLs and thank-you messages intended for legitimate users. As a result, unauthenticated visitors can exploit this vulnerability to gain insights into payment-gated forms without making an actual payment, raising serious concerns regarding data integrity and user privacy.

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.
