Detailsinfo

A vulnerability, which was classified as problematic, was found in Ninja Forms Plugin up to 3.14.9. Affected is the function _save_setting/insert_form_meta of the file Model.php/ImportForm.php of the component Import Processing. The manipulation of the argument settings with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability is traded as CVE-2026-15663 since 07/13/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation requires an enhanced level of successful authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/24/2026). This vulnerability is assigned to T1505 by the MITRE ATT&CK project.
