The WP Chat App plugin for WordPress is vulnerable to unauthorized plugin installation due to a missing capability check on the ajax_install_plugin() function in all versions up to, and including, 3.6.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install the filebird plugin.
The WP Chat App WordPress plugin before 3.6.5 does not sanitise and escape some of its settings, which could allow high privilege users such as admins to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed.
The WP Chat App WordPress plugin before 3.6.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admins to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
