Invicti identified possible phishing by navigating browser tabs but was unable to confirm the vulnerability.

Open windows with normal hrefs with the tag target="_blank" can modify window.opener.location and replace the parent webpage with something else, even on a different origin.

While this vulnerability doesn't allow script execution, it does allow phishing attacks that silently replace the parent tab. If the links lack rel="noopener noreferrer" attribute, a third party site can change the URL of the source tab using window.opener.location.assign and trick the users into thinking that they’re still in a trusted page and lead them to enter their sensitive data on the malicious website.

• Add rel=noopener to the links to prevent pages from abusing window.opener. This ensures that the page cannot access the window.opener property in Chrome and Opera browsers.
  
  
• For older browsers and in Firefox, you can add rel=noreferrer which additionally disables the Referer header.

<a href="..." target="_blank" rel="noopener noreferrer">...</a>
