Summary
The Ninja Forms – The Contact Form Builder That Grows With You plugin for WordPress is vulnerable to generic SQL Injection via Import File 'settings' Key in all versions up to, and including, 3.14.9 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The vulnerable keys originate from the 'settings' object in an attacker-controlled import file processed via file_get_contents() or base64-decoded/JSON-decoded blobs, bypassing wp_magic_quotes protections entirely; two distinct sinks are affected — _save_setting() in Model.php and insert_form_meta() in ImportForm.php — as only the value side is escaped while the key side receives no sanitization or parameterization at any point in the call chain.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
