Templates are created in the admin app and persisted in the API.
They are consumed:
- in the admin app, by requesting them from the API
- in the API, by loading them from the database
There are two potential places where unescaped HTML could be sent to a user:
- when the admin app is previewing a template (it has to render the template as
markup in order to show the placeholders)
- in the body of an email
For all consumers to have confidence that the templates are safe, it makes sense
to santitise them at the point of creation (and modification). This also avoids
any performance issues that could come from doing it at the point of requesting
a template.
In the future they could be created by a direct API call, bypassing the admin
app. Therefore it makes sense for the API to sanitise them.
The commit sanitises templates using a Mozilla’s Bleach library[1]. It is
configured to get the text content of the template, minus any HTML tags. It is
not using a regex because[2].

The commit sanitises templates using an XML parser. It extracts the text content
of the template, minus any HTML tags, because of this famous StackOverflow

- include travis build number
- renamed properties
- ELB version
- moved code all into health check
- changed health check to be on same URL for admin and api
This is checked on 3rd party API calls, but jobs (CSV files) were able expected to only allow valid files.
Change in tack means we want to have restricted notification failures reported in the UI.
