GHSA-9wmc-rg4h-28wv: github.com/kumahq/kuma affected by CVE-2023-44487

October 17, 2023 (updated October 13, 2025)

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.
