Update, patch or deactivate.
Update Boost to a release after 2.0.3, or disable and remove it until a fixed version is available.

Technical description
The Boost plugin for WordPress is vulnerable to time-based SQL Injection via the 'current_url' and 'user_name' parameters in versions up to, and including, 2.0.3 due to insufficient escaping on the user supplied parameters and lack of sufficient preparation on the existing SQL queries. 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.
