repo: Release v1.36.7

Summary of changes:

• Security fixes:

  • CVE-2026-47774: http2: HTTP/2 streams are now reset if they violate the configured maximum header list size. Uncompressed cookies now count towards mutable_max_request_headers_kb and max_headers_count limits, protecting against an HPACK cookie-bomb that could cause excessive memory usage. This can be reverted with envoy.reloadable_features.http2_include_cookies_in_limits.
  • oauth2: fixed a timing side-channel in HMAC verification that could leak HMAC secret validity.
  • oauth2: fixed a crash where AES-CBC decryption of token cookies could spuriously succeed (~1/256) on a secret mismatch, tripping a HeaderString validation assert.
  • CVE-2026-27135: http2: applied nghttp2 CVE-2026-27135 patch.

• Bug fixes:

  • load_report: fixed a shutdown race with ADS stream by introducing proper gRPC stream cleanup.
