No exploitation reported and no EPSS estimate yet.
The Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms plugin for WordPress is vulnerable to generic SQL Injection via Pattern JSON Keys/Values in all versions up to, and including, 5.1 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 editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
