CyberRota Analysis
AI-GeneratedThe Ninja Forms - Excel Export plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and lack of security checks in the save_filter() AJAX handler. This allows authenticated attackers with subscriber-level access or higher to inject malicious scripts that execute when users access affected pages. WordPress site administrators using this plugin should prioritize patching to mitigate potential exploitation risks.
Original NVD Description
The Ninja Forms - Excel Export plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.6. This is due to the save_filter() AJAX handler storing the raw $_POST['filter'] array into a WordPress option via update_option() without any capability check, nonce verification, or input sanitization, combined with the get_filter_row() method on the admin Excel Export screen concatenating the stored filter values (field_key, condition, value) directly into HTML attributes without esc_attr(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
