The BuddyPress WordPress plugin before 14.5.0 does not properly enforce authorization on its private messaging endpoints, allowing any authenticated user (Subscriber+) to read, modify, or delete other users' private messages.

The BuddyPress plugin for WordPress is vulnerable to Deserialization of Untrusted Data in all versions up to, and including, 14.5.0 This is due to the bpunserializeprofilefield() function using @unserialize() without the allowedclasses parameter on user-controlled XProfile field data. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary PHP objects via XProfile textbox fields, which could lead to remote code execution if a suitable POP chain is available in the WordPress environment.

The Block, Suspend, Report for BuddyPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link' parameter in versions up to and including 3.6.4. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with subscriber-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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 userid because the getitemspermissionscheck 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 escsql 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 userid parameter in the request. Attackers can pass another user's identifier to the getitempermissionscheck method, which validates the supplied userid 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.

WordPress Plugin Buddypress 6.2.0 contains a persistent cross-site scripting vulnerability that allows authenticated attackers with moderator privileges to inject malicious script code through the figure parameter in wp:html blocks. Attackers can inject iframe elements with event handlers like onload that execute when administrators or privileged users preview or view the affected page content, enabling session hijacking and persistent phishing attacks.

Attackers can modify the fieldhiddenfile and fielddeleteimg parameters during profile editing to unlink files from the server.

The BuddyPress Groupblog plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.9.3. This is due to the group blog settings handler accepting the groupblog-blogid, default-member, and groupblog-silent-add parameters from user input without proper authorization checks. The groupblog-blogid parameter allows any group admin (including Subscribers who create their own group) to associate their group with any blog on the Multisite network, including the main site (blog ID 1). The default-member parameter accepts any WordPress role, including administrator, without validation against a whitelist. When combined with groupblog-silent-add, any user who joins the attacker's group is automatically added to the targeted blog with the injected role. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate any user (including themselves via a second account) to Administrator on the main site of the Multisite network.

The Restrictions for BuddyPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the handleoptinoptout() function in all versions up to, and including, 1.5.2.

The BuddyPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘displayname’ parameter in versions up to, and including, 12.4.1 due to insufficient input sanitization and output escaping.
