CVE-2026-15602

NEX-Forms <= 9.2.4 - Authenticated (Admin+) SQL Injection via 'additional_params' Parameter

Published Aug 16, 2026 CVSS 3.1 · 4.9 Medium EPSS < 1% KEV · Not listed
Description
The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to generic SQL Injection via the 'additional_params' parameter in all versions up to, and including, 9.2.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with admin-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order vulnerability; the payload is stored via the submission_report2 AJAX handler (which lacks a nonce check and relies solely on a capability that can be configured down to subscriber-level) and triggered when a CSV export is generated.
