+A note on "Self XSS"
+--------------------
+
+Umbraco is a CMS, that allows users to edit content on a website. As such,
+all _authenticated users_ can:
+
+ - Edit content, and (depending on the field types) insert HTML and CSS in that
+   content, with a variety of allowed attributes.
+ - Depending on the user level: Edit template files, and insert C#, HTML, CSS and
+   javascript in so on.
+ - Upload files to the site, which will become publicly available.
+
+We see these functionalities as _features_, and not as security issues. Please
+report the mentioned items only if they can be performed by non-authorized
+users, or other exploitable vulnerabilities.
+
+Thanks!
