BuddyPress: Any authenticated attacker can enumerate another user's complete friend list via IDOR (CVE-2026-53675)
BuddyPress version 14.4.0 and earlier contains an insecure direct object reference (IDOR) vulnerability in its friends REST API. This flaw allows any authenticated user to enumerate the complete friend list of another user by querying the friends endpoint with an arbitrary user ID. The vulnerability exists because the permission check only verifies that the requester is logged in, without verifying ownership of the requested friend list. This leads to unauthorized disclosure of users' private social connections.
AI Analysis
Technical Summary
CVE-2026-53675 is an insecure direct object reference vulnerability in BuddyPress up to version 14.4.0. The friends REST API's get_items_permissions_check method fails to verify that the authenticated requester owns the friend list they are querying. As a result, any authenticated attacker can enumerate another user's entire friend list by supplying an arbitrary user_id parameter, exposing private social connection data.
Potential Impact
The vulnerability allows disclosure of private friend lists to any authenticated user without requiring elevated privileges. This compromises user privacy by exposing social connections that should remain confidential. There is no impact on integrity or availability reported.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, consider restricting access to the friends REST API or implementing additional access controls to prevent unauthorized enumeration of friend lists.
