DESCRIPTION:
A vulnerability has been reported in Google App Engine SDK for
Python, which can be exploited by malicious people to conduct
cross-site request forgery attacks.

The vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing proper
validity checks to verify the requests. This can be exploited to e.g.
execute arbitrary Python code if a user visits a specially crafted web
page.

The vulnerability is reported in version 1.5.3. Prior versions may
also be affected.

SOLUTION:
Update to version 1.5.4.
