Auth bypass in Rometheme Rtmkit

CVE-2026-5149

The RTMKit plugin for WordPress is vulnerable to Incorrect Authorization in all versions up to, and including, 2.0.7 This is due to the get_submission_content AJAX endpoint lacking a capability check to verify that a user has permission to access the requested form submission data.
