CVE-2026-1360
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.
