## Technical details

The NEX-Forms plugin for WordPress (versions up to 9.2.2) suffers from a missing authorization check (CWE-862). This vulnerability allows unauthenticated remote attackers to overwrite the 'saved_admin_email', 'saved_user_email', and 'saved_user_email_address' fields of arbitrary form entries. By manipulating these fields, an attacker can cause the site to dispatch attacker-controlled email content to arbitrary recipient addresses. The issue stems from the plugin failing to verify if a user has the necessary permissions to perform these specific update actions.
