CVE-2026-12998: Wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.55.0.2 via the 'draft' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to enumerate sequential integer entry IDs via the 'draft' parameter and read other users' saved draft form data, including names, email addresses, phone numbers, addresses, and free-form message content. This is only exploitable on forms that have the 'Save and Continue' feature enabled.
