The advisory
The WP Ultimate Review WordPress plugin before 2.4.5 does not neutralise shortcodes in all of the review fields submitted through its public review form, which is available to unauthenticated visitors, allowing them to execute arbitrary shortcodes when the affected field is displayed, provided user reviews and that field's display are enabled.
