BuddyPress <= 14.5.0 - Authenticated (Subscriber+) PHP Object Injection via XProfile Field Data

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 bp_unserialize_profile_field() function using @unserialize() without the allowed_classes 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.
