I was reading http://hackerific.net/2015/01/16/avoid-xss-in-template-toolkit/ Avoid XSS in Template Toolkit

and then it occured to me! Should you escape every place a template variable is used? I mean I have a site where you make a choice using a Jquery slider which is send to the server through AJAX POST, and then Template::Toolkit displays the value entered.

In essence there is no form POST where the user can enter data freely.But,can the user still manipulate the posted data and should I use escaping for the posted slider data? Shoudl I escape ALL data passed to Template toolkit or in certain cases ?
