CVE-2026-53673 · BuddyPress 14.4.0 Private Message IDOR via REST API user_id Parameter

This page contains facts from public vulnerability sources. Check the original advisory before updating.

BuddyPress 14.4.0 contains an insecure direct object reference vulnerability in the messages REST API that allows authenticated attackers to access arbitrary private message threads by supplying a user_id parameter in the request. Attackers can pass another user's identifier to the get_item_permissions_check method, which validates the supplied user_id instead of the logged-in user and is reused by the update and delete handlers, to read, reply to, or delete any user's private messages.
