Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2023-2114
CVSS 7.2 (High)
Publicly Published April 17, 2023
Last Updated January 22, 2024
Researcher Alexander Schmid

Description

The NEX-Forms plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 8.3.3 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 privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
