We used to be able to use a
|markdown
filter in our jinja templates which would turn markdown formatted strings into Markup strings as well as permit HTML tags.This opened us up to vulnerabilities where untrusted input might end up going through one of these filters and expose us to a cross-site scripting (XSS) exploit.
Going forward, markdown formatted text will be allowed in specific fields (documented in the README for digitalmarketplace-frameworks) and then rendered by TemplateFields, handled by the Content Loader.
