Input validation vulnerability in Event Manager, Events Calendar, Booking, Registrations and Tickets – Eventin 4.0.28

  • Severity: medium-risk
  • Status: Fixed
  • Publication: June 23, 2025

The Eventin plugin for WordPress, which includes the Event Manager, Events Calendar, Booking, Registrations, and Tickets features, has a security issue. This problem, called Reflected Cross-Site Scripting, affects all versions of the plugin up to and including 4.0.28. This means that the plugin does not properly clean or protect the information that is entered or displayed, which could allow hackers to inject harmful code into a webpage. This could happen if the user is tricked into clicking on a link.
