Potentially unsafe external link

[Gijutsu]

HTML links that open in a new tab or window allow the target page to access the DOM of the origin page using window.opener unless link type noopener or noreferrer is specified. This is a potential security risk.

Recommendation
Specify the link type by adding an attribute rel="noopener noreferrer".
