Last modified
CVE-2020-35470 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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).. EPSS estimates a 0.97% chance of exploitation in the next 30 days.
