CVE-2022-2600

The Auto-hyperlink URLs WordPress plugin through 5.4.1 does not set rel=noopener noreferer on generated links, which can lead to Tab Nabbing by giving the target site access to the source tab through the window.opener DOM object.

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.
