    CVE-2026-14558 (GCVE-0-2026-14558)

    Vulnerability from nvd – Published: 2026-08-28 06:00 – Updated: 2026-08-28 13:03

    Title
    WP User Frontend < 4.3.10 - Editor+ PHP Object Injection via AI Form Builder
    Summary
    The User Frontend WordPress plugin before 4.3.10 does not properly validate field type definitions and deserialises user-controlled post metadata when rendering submitted posts, allowing users with Editor-level access and above to inject arbitrary PHP objects, which can lead to remote code execution when a suitable POP chain is present on the site.
