python-django is vulnerable to web cache poisoning. An attacker may separate query parameters using a semicolon (;), causing a difference in the interpretation of the request between the proxy (running with default configuration) and the server resulting in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
