Vulnerability Overview

The External Links in New Window / New Tab WordPress plugin before 1.43 does not ensure window.opener is set to "null" when links to external sites are clicked, which may enable tabnabbing attacks to occur.

Technical Analysis

REMEDIATION: Update to version 1.43, or a newer patched version --- IDENTIFIER: CWE-1022 (Use of Web Link to Untrusted Target with window.opener Access) The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.
