Gutena's public nonce lets visitors trash arbitrary submissions

Gutena Forms through 1.9.0 exposes the gutena_Forms nonce through wp_localize_script() on public pages containing a form. An unauthenticated visitor can reuse it against management actions that lack authorization, changing any submission's read state or permanently trashing entries; exact action and identifier names are not disclosed.

CWE-862 — Missing Authorization

This CVE was published Aug 01, 2026 and is one of 2 known issues for this plugin.

What to do

Update, patch or deactivate.

Update to a corrected release after 1.9.0. Review submission status changes and deletions, restore trashed entries from trusted records where possible, and inspect public requests for entry enumeration.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical 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.

CVE / CNA vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
