Plan Envoy v1.39.1 patches multiple CVEs including HTTP/3 UAF and HTTP/2 crash
2026-08-31 · Releases: envoy · source ↗ #envoy#security#service-mesh
  • Platform/SRE — Plan: v1.39.1 fixes multiple CVEs in Envoy’s HTTP/3 (UAF, CVE-2026-73512), HTTP/2 (process termination, CVE-2026-73513), and connection-handling paths — real data-plane exposure for any Istio, Contour, or Envoy-based ingress deployment. None are KEV-listed or confirmed exploited, so schedule patching this sprint rather than treating it as an emergency.

Plan Envoy v1.38.4 patches 9+ CVEs including HTTP/3 UAF and HTTP/2 crash bugs
2026-08-31 · Releases: envoy · source ↗ #envoy#security#service-proxy
  • Platform/SRE — Plan: Envoy is a common data-plane component in service meshes and ingress layers; this patch addresses a use-after-free in HTTP/3, process-termination bugs in HTTP/2, and multiple URL-normalization bypasses. No KEV listing or known active exploitation, so no hard deadline, but upgrade to v1.38.4 should be scheduled this sprint for any fleet running Envoy.

Plan Envoy v1.37.6 patches nine CVEs including UAF and HTTP/2 crash bugs
2026-08-31 · Releases: envoy · source ↗ #envoy#security#service-mesh
  • Platform/SRE — Plan: Nine CVEs addressed including a UAF on HTTP/3, abnormal process termination on HTTP/2 trailers and ext_authz CONNECT requests, and a shared upstream connection-poisoning bug via HTTP upgrade — none are KEV-listed but the severity warrants scheduling an upgrade to v1.37.6 this sprint for any cluster running Envoy as ingress or data-plane proxy.

Plan archived Envoy v1.39.0: multiple CVE fixes, TLS and HTTP/2/3 breaking changes
2026-07-20 · Releases: envoy · source ↗ #envoy#security#service-mesh
  • Platform/SRE — Plan: v1.39.0 patches several CVEs across ext_authz, ext_proc, gRPC stats, and HTTP/2/HTTP/3 DoS vectors, but none are KEV-listed and EPSS is 0.00 — no hard deadline. Plan the upgrade this quarter, and validate the breaking TLS enforcement change and OpenTelemetry sampling behavior shift in staging before rolling to production.
