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

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Vulnity Security.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 1.4.4, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Vulnity Security to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Décio Brandão.

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.
