If a specific sequence of actions is performed when opening a new tab, the triggering principal associated with the new tab may have been incorrect. The triggering principal is used to calculate many values, including the Referer and Sec-* headers, meaning there is the potential for incorrect security checks within the browser in addition to incorrect or misleading information sent to remote websites.
