About the challenge:

  • The target is to pop an alert() on this host
  • Tested on Chrome 80.0.3987.163
  • No user interaction allowed
  • Lets imagine that all this pages has 'X-FRAME-OPTIONS: SAMEORIGIN' header and well-configured CSP :) So the solution is a link to this page, which triggers the alert, nothing more.

  • Solved by:

  • @insertScript unintended(fixed), intended
