Description
bbPress before 2.6.19 contains an information disclosure vulnerability that allows unauthenticated visitors to view restricted subforum posts because hide_sitewide ignores ancestor forum visibility. Topics and replies in public subforums nested under private or hidden parents expose title, permalink and body via the BuddyPress activity stream and REST endpoint.
