For silly reasons I ended up finding this slightly worrying bug in the code for this discussion site... Click on the textarea below: a javascript alert box should pop up. I have not tried, but this seems like a possible way to have code executed in people's browsers...

This is some random text </p> <hr /> <h2>Anton Geraschenko</h2> <p>Also, it appears that this keeps the input field from appearing (so I can only leave a comment by editing this entry). Also, all this text doesn't appear once I save this edit. This should definitely not happen.</p> </div> </li></ol> </div><div class="ContentInfo Middle"> <div class="PageInfo"> <p>1 to 1 of 1</p> <ol class="PageList PageListEmpty"> <li> </li> </ol> </div> </div><div class="ContentInfo Bottom"> <a href="../../../discussions/index.html" class="left">Back to Discussions</a> <a href="index.html#pgtop">Top of Page</a> </div></div> <a id="pgbottom" name="pgbottom"> </a> </div> </div></body> <!-- Mirrored from mathoverflow.tqft.net/discussion/279/this-should-not-happen/ by HTTrack Website Copier/3.x [XR&CO'2014], Sun, 04 Nov 2018 21:39:59 GMT --> </html>
