CVE-2026-74991 · Severity: medium · CVSS 6.8 · Published 2026-09-24

WPForms is a WordPress form builder plugin that integrates with Stripe for payment processing. The plugin fails to verify that Stripe payment objects belong to the current form before processing them, allowing an unauthenticated attacker to initiate refunds and cancel subscriptions on payments created by other applications connected to the site owner's Stripe account. This could result in unauthorized financial transactions and service interruptions for legitimate customers.
