What happened
Multiple Envoy releases (v1.35.11 → v1.38.2 series) containing important security fixes and related bug/feature changes. Notable security fixes include CVE-2026-47774: HTTP/2 streams are now reset when exceeding configured maximum header-list size and uncompressed cookies are counted toward header-size/header-count limits to mitigate an HPACK "cookie-bomb" (excessive memory/DoS risk). CVE-2026-27135: applied nghttp2 patch. OAuth2 fixes address a timing side-channel in HMAC verification (secret validity leakage) and an AES-CBC token-cookie decryption crash on secret mismatch. Other changes: RTD
