Summary
### Impact Envoy and Go HTTP/2 protocol stack is vulnerable to the "Rapid Reset" class of exploits, which send a sequence of HEADERS frames optionally followed by RST_STREAM frames. This can be exercised if you use the builtin gateway and receive untrusted http2 traffic. ### Patches https://github.com/kumahq/kuma/pull/8023 https://github.com/kumahq/kuma/pull/8001 https://github.com/kumahq/kuma/pull/8034 ### Workarounds Disable http2 on the gateway listener with a MeshProxyPatch or ProxyTemplate. ### References https://github.com/advisories/GHSA-qppj-fm5r-hxr3 https://github.com/golang/go/issues/63417 https://github.com/envoyproxy/envoy/security/advisories/GHSA-jhv4-f7mr-xx76 https://cloud.google.com/blog/products/identity-security/how-it-works-the-novel-http2-rapid-reset-ddos-attack https://www.nginx.com/blog/http-2-rapid-reset-attack-impacting-f5-nginx-products/?sf269548684=1 https://www.envoyproxy.io/docs/envoy/latest/configuration/best_practices/edge
