Reverse Tabnabbing

  • Risk:

  • Medium

  • Type:
  • Passive
Summary

At least one link on this page is vulnerable to Reverse tabnabbing as it uses a target attribute without using both of the “noopener” and “noreferrer” keywords in the “rel” attribute, which allows the target page to take control of this page.

Solution

Do not use a target attribute, or if you have to then also add the attribute: rel="noopener noreferrer".
