CVE-2026-3359

CVE-2026-3359 is a SQL injection vulnerability (CWE-89) affecting the Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress in versions up to and including 1.15.42. The issue stems from insufficient escaping of the user-supplied 'inputs' parameter and lack of sufficient preparation in the existing SQL query, enabling attackers to append additional SQL queries to extract sensitive information from the database. The vulnerability was published on 2026-05-05 and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. By crafting malicious requests targeting the 'inputs' parameter, they can inject SQL payloads into existing queries, achieving high-impact confidentiality violations such as dumping sensitive database contents, including user data or other site information.
