## Technical details

The Ninja Forms plugin for WordPress is vulnerable to a generic SQL Injection via the 'settings' key in form import files in versions up to 3.14.9. The vulnerability exists because the plugin fails to sanitize or parameterize the key side of the 'settings' object during the import process, even though the value side is escaped. Specifically, the sinks _save_setting() in Model.php and insert_form_meta() in ImportForm.php are affected. Because the data is processed via file_get_contents() or decoded from JSON/base64 blobs, it bypasses standard WordPress magic quotes protections. An authenticated attacker with administrator privileges can exploit this to append SQL queries and extract sensitive information from the database.
