Technical details
The plugin fails to properly sanitize shortcodes in user-submitted review fields before storing and displaying them. An unauthenticated attacker can inject malicious shortcodes via the public review form; when the affected review field is rendered on the website, the shortcode executes with the privileges of the WordPress site. A fix is available in version 2.4.5.
