What is CVE-2026-14567?

The User Frontend plugin for WordPress versions prior to 4.3.10 suffers from an access control vulnerability, where the user directory search endpoint lacks proper authentication mechanisms. This oversight permits unauthorized attackers to indiscriminately access sensitive information, including email addresses and phone numbers of all registered users, potentially compromising user privacy and security.

Affected Version(s)

User Frontend 4.3.0 < 4.3.10

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
