Buddypress

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.

BuddyPress 14.4.0 contains a regular expression injection vulnerability in the activity mention resolver that, when username compatibility mode is enabled, allows attackers to manipulate a REGEXP database clause by crafting mention names containing regex metacharacters. Attackers can submit @mentions whose metacharacters pass through esc_sql unescaped and are inserted into an unprepared REGEXP query against the users table, enabling boolean-based inference of usernames and denial of service through catastrophic backtracking.

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.

The BuddyPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘display_name’ parameter in versions up to, and including, 12.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
