If you run the example blog application via

mvn archetype:generate -DarchetypeGroupId=org.ninjaframework -DarchetypeArtifactId=ninja-servlet-jpa-blog-archetype

then the example application has a persistent cross site scripting vulnerability. You can reproduce this behavior if you create a new blog entry with

<script>alert('xss')</script>

Wonderful finding! Would you mind fixing the archetype?

No HTML is being escaped after update to the latest version of freemarker as it changed various things . See my pull request for a way around this.
