Description

The Eventbee Ticketing Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'eventbeeticketwidget' shortcode in all versions up to, and including, 1.0. This is due to the plugin not properly sanitizing user input and output of several parameters. 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.
