Advisory

Source description from Wordfence Intelligence, credited to Lenon Leite.

The Simple Personal Message plugin for WordPress is vulnerable to SQL Injection via the ‘message’ parameter in versions up to 2.0.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with low-level privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
