CVE-2020-35470
First published: Tue Dec 15 2020(Updated: )
Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters).
