What the vulnerability does
01Description
The Filter & Grids plugin for WordPress is vulnerable to SQL Injection via the 'phrase' parameter in all versions up to, and including, 3.2.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This only works on MariaDB as the query results in a syntax error on MySQL.
Explanation of Vulnerability in Simple Terms

An attacker with network access can craft malicious input to read sensitive data from the database, such as user credentials or configuration details.
