Remedy

  • 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.

Unsure www.limesurvey.org is an untrusted target?

I didn't set as private since it's included in core and not a way to add such link by simple user of limesurvey instance.
