## Description

The BuddyPress Group Reviews plugin for WordPress is vulnerable to unauthorized access of data via the group reviews REST API routes, the BuddyPress groups REST response, the bp_group_review_filter_ratings AJAX action, the review widgets, the schema markup and the group header rating output in all versions up to, and including, 3.9.0, due to a missing group visibility check (the review REST read routes used a permission callback that always returned true). This makes it possible for unauthenticated attackers to read reviews, ratings and review counts of private and hidden groups they are not members of.
