Istio reports :

Two security vulnerabilities have recently been identified in the Envoy proxy. The vulnerabilities are centered on the fact that Envoy did not normalize HTTP URI paths and did not fully validate HTTP/1.1 header values. These vulnerabilities impact Istio features that rely on Envoy to enforce any of authorization, routing, or rate limiting.
