Unsafe Cross-Origin Links

.

How to Fix

In order to pass this test, you have to update each link identified in this report, by adding a rel="noopener" or a rel="noreferrer" attribute or both:

< a href="https://example.com" target="_blank" rel="noopener noreferrer" > Click here < /a >

rel="noopener" prevents the new page from being able to access the window.opener property and ensures it runs in a separate process.

rel="noreferrer" has the same effect but also prevents the Referer header from being sent to the new page.
