I know JZ, but this vulnerability is in the post and no in the template.
And this could be generated by blogger and affect to administrator!
The blogger can edit, but haven't admin. If the blogger post some script,
this affect to administrator.

posts; our take on this is that blogs are user-generated content, not
different from any third-party website on the Internet. Naturally, for your
safety, we do employ spam and malware detection technologies - but we
believe that the flexibility in managing your own content is essential to
the success of our blogging platform.
*Therefore, the ability to execute owner-supplied scripts on your own
blog is not considered to be a vulnerability. That being said, the ability
qualify for a reward!

Today, I going to shared with you about XSS in blogger. This is a very
simple, but isn´t fix yet..
This bug could be exploited by bloggers without administrator permissons.
Steps to reproduce the XSS:
1.- Create a new post in the blog and insert some script

2.- When the administrator enter in the administration panel in
"templates" section, blogger automatically executed the script, because
blogger have a mini-preview in "Ahora en el blog", then execute the script

3.- Ready! the script has been executed!
