CVE-2026-15161 Details
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.
A stored cross-site scripting vulnerability has been identified in the Ninja Forms - Excel Export plugin for WordPress, affecting versions through 3.3.6. The issue arises because the save_filter() AJAX handler saves the raw filter data into a WordPress option without proper capability checks, nonce verification, or input sanitization. This unsanitized data is then retrieved and directly inserted into HTML attributes on the admin Excel Export screen, creating an opportunity for authenticated attackers with subscriber-level access or higher to inject and execute arbitrary scripts on pages viewed by users.
Users can update to version 3.3.7 or a newer patched version to address this vulnerability.
