Hi devs,

This needs an update.

Bug 13618 has been pushed to master.
Now you will have to escape all the variables template-side.
See the wiki page to understand why and how - https://wiki.koha-community.org/wiki/Coding_Guidelines#HTML9:_filter_all_the_variables

There is a test in the QA script (missing_filter) as well as a test in the codebase to catch missing filters (xt/find-missing-filters.t)

To make things easier you can use the misc script (misc/devel/add_missing_filters.pl) to automatically add the missing filters!

Cheers,
Jonathan
