Summary
The Custom 404 Pro plugin for WordPress is vulnerable to time-based SQL Injection via the 'path' parameter in all versions up to, and including, 3.12.0 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 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.
Risk Assessment
An attacker with administrator privileges can access sensitive data in the WordPress database.
Recommendation
Update the Custom 404 Pro plugin to a version newer than 3.12.0 if available, or consider removing/deactivating it until a fix is released.
