9.1
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2024-31356
CVSS 9.1 (Critical)
Publicly Published April 7, 2024
Last Updated May 28, 2024
Researcher Muhammad Daffa

Description

The User Activity Log plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 1.9 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.
