Executive brief
Hide My WP Ghost is a WordPress plugin that conceals the location of the WordPress login page and other sensitive URLs to prevent brute-force attacks. A vulnerability in versions before 7.0.11 allows attackers to bypass the security checks protecting this hidden login page by submitting a specially crafted loopback verification request with incorrect or missing credentials, re-exposing the concealed login URL to anyone visiting the site.
Technical details
The vulnerability is an authentication bypass in the plugin's loopback security-check mechanism. The plugin fails to properly validate the verification token on requests that are intended to check server connectivity from the local machine; an attacker can trigger these checks with invalid or missing verification values, causing the plugin to temporarily disable its login and URL hiding protection. This is a logic flaw in the security check conditional, allowing unauthenticated, network-reachable attackers to re-expose the hidden WordPress login page location. The vulnerability was patched in version 7.0.11.
