The vulnerability is at the level of the interpretation of the "titre",

Indeed, the insertion of a hostile code script in this field makes it
possible to a malicious user to carry out this script on the navigator
of the visitors.
The hostile code could be :
[script]alert("Cookie="+document.cookie)[/script]
(open a window with the cookie of the visitor.)
