CVE-2020-8660

CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed not recognized as a TLS client by a client using only TLS 1.3. Because TLS extensions SNI, ALPN were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some...
