## Description

The We’re Open! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'content' parameter of the we_are_open_wp_ajax AJAX action in all versions up to, and including, 2.6, due to insufficient input sanitization and output escaping. The submitted content is returned unfiltered in a JSON response served as text/html. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in a user's browser if they can trick the user into submitting a crafted request, such as by visiting a malicious page.
