Relevanssi <= 4.24.4 (Free) and <= 2.27.5 (Premium) - Unauthenticated SQL Injection
Vulnerability Description
The Relevanssi – A Better Search plugin for WordPress is vulnerable to time-based SQL Injection via the cats and tags query parameters in all versions up to, and including, 4.24.4 (Free) and <= 2.27.5 (Premium) due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
