Even if the parser is perfect, you can trick applications into including

anywhere?
Even if the parser is perfect, these attacks can subvert the
applications that use the XML. For example, you can send a SQL injection
attack inside an XML element to a web service that is backed by a
database. I've found this flaw in several commercial products.
Even if the parser is perfect, XSS attacks inside XML or XML fragments
can compromise the browser's security. Virtually every "Web 2.0"
application has this flaw, whether they use REST or SOAP, JSON or XML --
because a lot of it ends up in the browser eventually.
And this has what to do with the issue of CDATA sections?
If a security person wants to look inside the file, they need to usean XML parser.
Agreed. And they get some assurance that the parsing worked. But they
get no assurance that the data inside the document is safe to use.
And this has what to do with the issue of CDATA sections?
