We recently identified an interesting code execution vulnerability in the Google App Engine SDK for Python. By combining a CSRF vulnerability in the administration web UI, with some other unique vulnerabilities we found in the Google python libraries, a remote hacker could gain remote code execution privileges on victim's machine. This vulnerability affects all operation systems running Google App Engine SDK for python (i.e. Windows, Mac OS, etc.).
