CVE-2026-1360BuddyPress <= 14.5.0 - Authenticated (Subscriber+) PHP Object Injection via XProfile Field Data

Description

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.

Data: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Published as the sources state it, in English.
