Description Andrej Nemec 2016-12-19 09:06:35 UTC 
Due to incorrect HTTP conditional request handling Squid can deliver responses containing private data to clients it should not have reached.

This problem allows a remote attacker to discover private and sensitive information about another clients browsing session. Potentially including credentials which allow access to further sensitive resources.
