CyberRota Analysis
AI-GeneratedThe Events Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to inadequate input sanitization and output escaping of the 'header_format' parameter in versions up to 7.4.0.1. This flaw allows unauthenticated attackers to inject malicious scripts into web pages, potentially compromising users who interact with affected links. WordPress site administrators using this plugin should prioritize applying updates or implementing mitigations to protect against potential exploitation.
Original NVD Description
The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'header_format' parameter in all versions up to, and including, 7.4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The shortcode entry point sanitizes 'header_format' via wp_kses(), but the unauthenticated 'search_events_grouped' AJAX action bypasses this sanitization entirely, leaving the parameter unsanitized before it is echoed into the HTML body in output_grouped().
