Description
The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'etn_shedule_objective' schedule_slot Parameter in all versions up to, and including, 4.1.23 due to insufficient input sanitization and output escaping.
