CVE-2022-1583

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.

Weakness

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.

Affected Software

Potential Mitigations

• When creating a link to an external document using the tag with a defined target, for example “_blank” or a named frame, provide the rel attribute with a value “noopener noreferrer”.
• If opening the external document in a new window via javascript, then reset the opener by setting it equal to null.
• Do not use “_blank” targets. However, this can affect the usability of the application.
