Authorization Bypass in Gutena Forms WordPress Plugin

Publication date: 2026-08-01

Last updated on: 2026-08-01

Assigner: Wordfence

Description
The Gutena Forms – Contact Form, Survey Form, Feedback Form, Booking Form, and Custom Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.9.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to modify the read/unread status of or permanently trash arbitrary form submission entries belonging to any form. The nonce issued by check_ajax_referer() does not function as an authorization barrier because the nonce action 'gutena_Forms' is emitted to unauthenticated visitors via wp_localize_script() on any public page that contains a Gutena Forms block, making it freely obtainable by anonymous attackers.

Executive Summary

This vulnerability is an authorization bypass in the Gutena Forms WordPress plugin up to version 1.9.0. It allows unauthenticated attackers to modify the read/unread status or permanently delete form submissions from any form on the site. The issue occurs because the plugin emits a nonce action 'gutena_Forms' via wp_localize_script() on public pages, which attackers can obtain and misuse to bypass authorization checks.

Detection Guidance

Check WordPress sites using Gutena Forms plugin versions up to 1.9.0. Look for unauthorized changes to form submission statuses or deletions. Review server logs for suspicious AJAX requests targeting Gutena Forms endpoints.

Impact Analysis

If exploited, this vulnerability could allow attackers to delete or mark as read/unread any form submissions on your WordPress site without authentication. This could lead to loss of important user data, such as contact form submissions, survey responses, or booking requests, potentially disrupting business operations or causing data loss.

Compliance Impact

This vulnerability could impact compliance with GDPR and HIPAA by allowing unauthorized deletion or alteration of user-submitted data. GDPR requires data integrity and protection, while HIPAA mandates secure handling of protected health information. Unauthorized modifications or deletions could violate these regulations, leading to legal consequences or fines.

Mitigation Strategies

Update Gutena Forms plugin to the latest version immediately. If update is unavailable, disable the plugin until a patch is released. Monitor form submissions for unauthorized changes.
