Critical Formidable Forms Payment Flaw
As an expert branding content curator, I urge site owners to read this urgent report now. A pervasive bug in Formidable Forms permits unauthenticated attackers to mark expensive purchases as paid. This flaw affects versions up to 6.28, and it allows PaymentIntent reuse to bypass proper validation. The risk to revenue and brand trust is immediate, this is not a theoretical issue.
I highlight concise, technical details that matter to developers and leaders. Read why missing validation in handle_one_time_stripe_link_return_url enables this payment bypass. The verify_intent function validates client secret ownership, it does not confirm amounts or link intents to submissions. Attackers can reuse a low charge PaymentIntent to mark a higher charge as paid. Timely updates protect revenue, customer trust and your brand reputation. Act now.
As a curator, I recommend immediate review of plugin versions and payment logs for anomalies. If you use Stripe with Formidable Forms, prioritize updating to version 6.29 or newer. This article explains technical findings and practical mitigation steps, it will save hours of triage. Read the full post to equip your team with precise fixes and verification checks. Protect margins, customers, and trust today.
