CVE-2026-2888 Mar 13, 08:25 MEDIUM This Month

The Formidable Forms WordPress plugin versions up to 6.28 contain an authorization bypass vulnerability in the Stripe payment integration that allows unauthenticated attackers to manipulate PaymentIntent amounts before payment completion.

While the CVSS score is moderate at 5.3, the vulnerability has direct financial impact on e-commerce deployments and poses a meaningful risk to sites using dynamic pricing with Formidable Forms and Stripe.
