Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2023-39309
CVSS 8.8 (High)
Publicly Published August 10, 2023
Last Updated August 14, 2023
Researcher Rafie Muhammad - Awesome Motive, Inc.

Description

The Fusion Builder plugin for WordPress is vulnerable to SQL Injection via an unknown parameter in versions up to, and including, 3.11.1 due to insufficient escaping on a user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
