Recently I've been busy with my new little project. What started out as a proof of concept suddenly became good enough to demonstrate it with Kyle Osborn at BlackHat, so I decided I might just present it here too ;)
This is a security advisory for popular PHP framework - CodeIgniter. I've found several bypasses in xss sanitization functions in the framework. These were responsibly disclosed to the vendor and are now fixed in version 2.1.2. (CVE-2012-1915).
