🔍 **CWE-250 (Missing Authorization Check)**: The NF5_Export_Forms class constructor does not verify user permissions, permitting unauthorized access.

💻 **Affects All Versions**: Including version 9.1.8 and earlier, all WordPress sites using the NEX-Forms plugin are impacted.

🔐 **No Authentication Required**: Attackers can enumerate the `nex_forms_Id` parameter to export form configurations and retrieve third-party keys, API credentials, etc.

⚠️ **Very Low Barrier to Entry**: No login or special configuration required; exploitation can be triggered simply by accessing a specific URL parameter.

❌ **No Public PoC**: No known exploit code or in-the-wild attack reports exist currently, but exploitation is theoretically possible.

🔍 **Self-Check Method**: Verify if the NEX-Forms plugin is installed and if the version is ≤9.1.8; scan the website for the existence of the `/wp-admin/admin-ajax.php?action=nex_forms_export_form` endpoint.

🛠️ **No Official Fix**: As of 2026-01-31, no patch has been released, and the vulnerability remains unaddressed.

🛡️ **Temporary Mitigation**: Disable the plugin, restrict access to admin-ajax.php, or add firewall rules to block requests containing `nex_forms_export_form`.

🔥 **High Priority**: High risk of sensitive data exposure; immediate investigation and plugin upgrade or disablement is recommended.
