CVE-2026-89101

Description

The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.6.2 via the get_entry due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with custom-level access and above, to view, read, and permanently delete forms and entries belonging to any other user — including personally identifiable information submitted through public contact and lead forms — regardless of form ownership.
