There is and a XSRF under Dean's Permalinks Migration Plugin version
1.0 which allow any attacker to conduct the user to do and a
unsolicited action this combined within a XSS bug (also found) in the
plugin allows and attacker to gain valid credentials for the WordPress
Since the variable $dean_pm_config['oldstructure'] its not correctly
sanitized (when retrieving), this allow any user to store/save
"malicious code" inside the database and later be injected this
"malicious code" when the data is retrieved.
Using the XSRF as a "combo" we can create crafted pages that will
force users to conduct this injection and steal some valid credentials
to the WordPress based CMS.
This is a very innocent and short PoC...

Since i couldn't contact the plugin author by any of the public ways
that he left on his website this force me to make and release and a
special sub-version for the plugin, version which i call 1.1-gx...
This version adds the need protection against the vulnerability and
uses some of the WordPress coding standards suggest by the WordPress
