Low risk26th percentile - higher than 26% of all known CVEs
Summary
The NEX-Forms plugin for WordPress up to version 9.2.4 is vulnerable to generic SQL Injection via the 'additional_params' parameter. Insufficient escaping and lack of query preparation allow authenticated attackers with admin-level access to append additional SQL queries. This is a second-order vulnerability triggered during CSV export.
Risk Assessment
The organization may lose sensitive database data. Attackers with admin privileges can extract data, and the lack of nonce in the AJAX handler increases risk.
Recommendation
Update the NEX-Forms plugin to the latest version. Restrict admin privileges and monitor CSV exports.
Original NVD description (English source)
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.
