# Forminator Forms WordPress plugin: unpaid users see post-payment content

Link for people: https://infrastack.ai/live/CVE-2026-111597 (this .md is for agents)

The Forminator Forms WordPress plugin before 1.58.4 does not check that a Stripe Checkout payment has completed before returning the after-payment response for a pending form submission. An unauthenticated visitor can get the post-payment redirect URL and thank-you message of a payment-gated form without paying.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Forminator version in the WordPress admin plugin list, or with `wp plugin get forminator --field=version`
- Look for payment-gated forms that use Stripe Checkout

## Fix
