Overview

We need to fix a potentially unsafe external link by adding the attribute rel="noopener noreferrer". The problem and solution are similar to those detailed in the CodeQL alerts tracked in #5129; however, the instance addressed by this issue did not result in a CodeQL alert.

Action Items

• Open the file _includes/about-page/about-card-sponsors.html in your IDE
• Replace

<a href="https://www.sipandsonder.com" target="_blank" alt="Sip and Sonder">

with

<a href="https://www.sipandsonder.com" target="_blank" alt="Sip and Sonder" rel="noopener noreferrer">

• Using Docker, check the /about page and confirm that the page remains the same in mobile, tablet, and desktop views as on the current website.
• Confirm that the Sip and Sonder link still works and opens as expected.
