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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
