Vulnerability Title
BuddyPress 14.4.0 Friends List IDOR via REST API
Source: NVD (National Vulnerability Database)
Vulnerability Description
BuddyPress 14.4.0 contains an insecure direct object reference vulnerability in the friends REST API that allows 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.
