Published Sep 15, 2026 · Updated Sep 16, 2026 · Assigned by Wordfence

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. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
