Description

CVE-2026-5127 is a high-severity vulnerability in the WordPress plugin 'User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration' up to version 4.3.1. It involves deserialization of untrusted data via the wpuf_files parameter during form submission, allowing authenticated users with Subscriber-level access or higher to inject arbitrary PHP objects. This can lead to arbitrary code execution, file deletion, or other malicious actions if a suitable POP chain exists on the target system. No official patch or remediation guidance is currently available.
