Code injection

Time Tracker is an open source time tracking system. The week view plugin in Time Tracker versions 1.22.11.5782 and prior was not escaping titles for notes in week view table. Because of that, it was possible for a logged in user to enter notes with elements of JavaScript. Such script could then be executed in user browser on subsequent requests to week view. This issue is fixed in version 1.22.12.5783. As a workaround, use htmlspecialchars when calling $field->setTitle on line #245 in the week.php file, as happens in version 1.22.12.5783.
