Summary
The Gutena Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to and including 1.9.0 due to improper verification of user permissions. This allows unauthenticated attackers to modify the read/unread status or permanently trash arbitrary form submission entries.
Risk Assessment
An attacker can manipulate form submissions without authorization, potentially leading to data loss or disruption of business processes. The nonce used in check_ajax_referer() is exposed to unauthenticated users on public pages, facilitating the attack.
Recommendation
Immediately update the Gutena Forms plugin to the latest version that fixes this vulnerability. Also consider implementing additional authorization mechanisms for AJAX actions.
Other vulnerabilities in Gutena Forms
Original NVD description (English source)
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.
