The plugin does not validate and escape some of its post meta before outputting them back in a page/post, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

1. Add an event in the plugin with a city meta as: " onmouseover="alert(1)"

2. On a new page, add the [event-list] shortcode.

3. Hover the mouse on the content displayed by shortcode to trigger the XSS.

Dependency: WooCommerce plugin.
