What is CVE-2026-82844?

The WPForms Lite plugin for WordPress, prior to version 2.0.2.2, contains a significant vulnerability that allows unauthenticated users to submit forms using the PayPal Commerce gateway without completing the payment process. This flaw results in the possibility of users receiving confirmation messages and notification emails, despite the absence of any actual payment transaction being recorded at the payment provider. Consequently, websites utilizing this plugin may experience unauthorized submissions, undermining the integrity of their payment systems and potentially leading to financial losses and reputational damage.

Affected Version(s)

WPForms Lite 1.10.0.1 < 2.0.2.2
