Vulnerable Version 9.2.2

Patched Version 9.2.3

Disclosed June 25, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-12404:

This vulnerability is a missing authorization issue in the NEX-Forms plugin for WordPress, affecting all versions up to and including 9.2.2. The plugin fails to verify user identity or permissions before allowing CSV export of form submission data. Unauthenticated attackers can enumerate sequential report IDs and download complete form submissions, including sensitive personal and payment data. The CVSS score is 5.3, classified under CWE-862 (Missing Authorization).

The root cause lies in the CSVExport class constructor located in main.php at lines 3650-3668. The vulnerable code checks for the ‘export_csv’ request parameter and immediately calls generate_csv() without any authentication or authorization checks. Specifically, the code at line 3651 reads $_REQUEST[‘export_csv’] and at line 3653 calls $this->generate_csv() if the parameter is set. There are no calls to is_user_logged_in(), current_user_can(), or wp_verify_nonce() before the export operation. The export functionality processes sequential report IDs via the ‘report_Id’ parameter, as seen in the URL structure ‘admin.php?page=nex-forms-dashboard&export_csv=true&report_Id=’.$set_report_id.

An attacker can exploit this vulnerability by sending a crafted HTTP request to the WordPress admin area without authentication. The attack vector is a direct HTTP GET or POST request to /wp-admin/admin.php with parameters ‘page=nex-forms-dashboard’, ‘export_csv=true’, and ‘report_Id=N’, where N is a sequential numeric ID. Since no authentication is required, the attacker can iterate report IDs starting from 1 to enumerate all saved reports. The CSV export functionality in generate_csv() at line 3712 outputs form submission data including names, email addresses, phone numbers, postal addresses, payment details, and uploaded file paths.

The patch addresses the vulnerability by adding three authorization checks in the CSVExport class constructor. The first check at line 3697 verifies the user is logged in using is_user_logged_in(). The second check at line 3705 verifies the user has ‘manage_options’ capability using current_user_can(). The third check at line 3713 verifies a nonce using wp_verify_nonce() with the nonce parameter ‘_wpnonce’ against action ‘nf_export_csv’. The patch also modifies URL generation in class.dashboard.php to include the nonce in export links, and updates the export link in extra_buttons to use the nonce-protected URL.

Successful exploitation allows an unauthenticated attacker to extract all stored form submission data from the WordPress site. This data can include personally identifiable information (PII) such as names, email addresses, phone numbers, and postal addresses. More critically, it can include payment details and file paths to uploaded documents, which could expose sensitive financial information or provide access to uploaded files. The attacker can systematically enumerate all report IDs, potentially compromising every form submission stored on the site. This represents a complete breach of data confidentiality for all form submissions.
