  • Create a parent page A with a child page B
  • Add an {{{excerpt}}} macro to B containing the text {{<script>alert("Gotcha!");</script>}}
  • Add the {{{children}}} macro to page A, with "Show excerpts" checked
  • Alert is shown when viewing A

This is currently present on EAC - likely to be in released versions; not tested yet.

Found by [~dpabst] and me during QA :)
