content)

 Severity:  normal        |   Keywords:  needs-patch

 I'm using version 3.4.1

 For ex: we have this article on WPBeginner

 http://www.wpbeginner.com/wp-tutorials/how-install-wordpress-cdn-solution-
 maxcdn/

 Anyone can simply add:

 http://www.wpbeginner.com/wp-tutorials/how-install-wordpress-cdn-solution-
 maxcdn/345/

 This will resolve the post with the rel="canonical" for the new page which
 creates duplicate content.

 I tried this with @JJJ at WordCamp columbus. This only works with numbers
 not letters or characters. It has to do something with post pagination
 even though the article is not split into pages.
