Here we go, next step then.
As we did not fix the performance issue when autofiltering
the variables (see bug 20975), the only solution we have is to add the
filters explicitely.
This patch has been autogenerated (using add_html_filters.pl, see next
pathces) and add the html filter to all the variables displayed in the
template.
Exceptions are made (using the new 'raw' TT filter) to the variable we
already listed in the previous versions of this patch.
To test:
- Use t/db_dependent/Koha/Patrons.t to populate your DB with autogenerated
data which contain <script> tags
- Remove them from borrower_debarments.comments (there are allowed here)
update borrower_debarments set comment="html tags possible here";
- From the interface hit page and try to catch alert box.
If you find one it means you find a possible XSS.
To know where it comes from:
* note the exact URL where you found it
* note the alert box content
* Dump your DB and search for the string in the dump to identify its
location (for instance table.field)
Next:
* Ideally we would like to use the raw filter when it is not necessary
to HTML escape the variables (in big loop for instance)
* Provide a QA script to catch missing filters (we want html, uri, url
or raw, certainly others that I am forgetting now)
* Replace the html filters with uri when needed (!)

This patch is a reimplementation of the original from Indranil Das Gupta
and the QA follow-up from Julian Maurice. Original test plan:
Conformance rules for HTML5 is generating warnings for <script> element
with type="text/javascript" attribute when the OPAC page is checked
with W3C Validator. This patch removes the cause of these warnings.
Test plan
=========
1/ Paste the URL to your OPAC page (if it is hosted) to W3C Validator
and watch about 10+ warnings being generated by the validator.
2/ Apply patch and re-submit the page to the Validator. The warnings
would be gone.

Having to write [% KOHA_VERSION %] for each url is bad because:
- It's easily forgettable when adding new <script> or <link>
- It prevents grep'ing for the full filename
- It violates the DRY principle
- If at some point we want to change the "force js and css reload"
mechanism, it will be tedious
This patch:
- adds a Template::Toolkit plugin that generates <script> and
<link> tags for JS and CSS files, and inserts automatically the Koha
version in the filename
- use the new plugin to remove all occurences of [% KOHA_VERSION %]
- remove the code that was adding KOHA_VERSION as a template variable
Test plan:
1. Apply patch
2. Go to several different pages in Koha (opac and intranet) while
checking your browser's dev tools (there should be no 404 for JS and
CSS files, and the Koha version should appear in filenames) and the
server logs (there should be no "File not found")
3. `git grep KOHA_VERSION` should return nothing
4. prove t/db_dependent/Koha/Template/Plugin/Asset.t
