CVE-2026-75903

Vulnity Security <= 1.4.3 - Unauthenticated Authentication Bypass to Administrator via Exposed Pairing Credentials

Published Oct 16, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
The Vulnity Security plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.4.3 This is due to insufficient protection of the delegated-login pairing credential file on Nginx-based installations, where the plugin's generated server configuration snippet guards the wrong directory path. This makes it possible for unauthenticated attackers to retrieve the stored credentials, forge signed REST API requests, and log in as an administrator.
