CVE-2026-82844

MEDIUM 5.3 PoC AVAILABLE

Published 2026-10-14 · Last modified 2026-10-14

The WPForms Lite WordPress plugin before 2.0.2.2 does not verify server-side that a payment was completed before accepting a submission on forms using its PayPal Commerce gateway, allowing unauthenticated visitors to submit paid forms without paying. The form's confirmation is delivered and its notification emails are sent even though no order exists at the payment provider and no payment is recorded.
