WordPress Vulnerabilities Digest - April 2021 Part 2
The WordPress Vulnerability Roundup is divided into three different categories: WordPress core, WordPress plugins, and WordPress themes.
WordPress Core Vulnerabilities
Great news! No new WordPress core vulnerabilities have been disclosed this month.
The latest version of WordPress is currently 5.7. Make sure all your websites are running the latest version of WordPress core.
WordPress Plugin Vulnerabilities
1. iThemes Security Free & Pro
Vulnerability: Hide Backend Bypass Patched in Version (iThemes Security): 7.9.1 Patched in Version (iThemes Security Pro): 6.8.4 Severity: High
The Hide Backend feature in iThemes Security allows users to hide the login page by changing its name and preventing access to wp-login.php and wp-admin. A bug was discovered in versions below 7.9.1 of iThemes Security and below 6.8.4 of iThemes Security Pro that make the hidden login page discoverable, reducing the effectiveness of the feature.
Update to version 7.9.1 of iThemes Security and 6.8.4 of iThemes Security Pro to receive the Hide Backed bypass workaround patch.
Note: You should be aware that the hide backend feature isnt full-proof no matter how much we try to improve it. In fact, the effectiveness of hiding the login page of your website for security reasons is our #1 WordPress security myth. Why? The truth is that you cant completely hide the backend of your website. The login page may be exposed by WordPress core, plugins, or themes when printing links to the login page (like Privacy Request Confirmations or front-end login forms).
