## Description

The Events Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'event_rsvp_date' parameter in all versions up to, and including, 7.4.8 due to insufficient input sanitization (only wp_kses_data was applied) and missing output escaping when the value is printed into an input attribute of the event bookings form. This makes it possible for authenticated attackers, with contributor-level access and above who can edit events, to inject arbitrary web scripts that execute whenever a user accesses the event editing form.
