CVE-2026-53675 BuddyPress CVE debrief

CVE-2026-53675 is a MEDIUM-severity vulnerability in BuddyPress 14.4.0. The vulnerability is an insecure direct object reference in the friends REST API, allowing any authenticated attacker to enumerate another user's complete friend list. Attackers can query the friends endpoint with an arbitrary user_id because the get_items_permissions_check method only verifies that the requester is logged in and never checks ownership of the requested list, resulting in disclosure of users' private social connections.
