SQL Injection in Eventon - Subscriber

CVE-2026-93300

The EventON - Subscriber plugin for WordPress is vulnerable to generic SQL Injection via the 'email' parameter in all versions up to, and including, 1.4.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
