- Platform/SRE — Act: The eMudhra intermediate CA private keys are confirmed compromised, enabling potential MITM against any service trusting those CAs; upgrade Envoy to v1.40.1 now to remove trust in those CAs from the proxy trust store. If running Istio, also review the peer metadata label-fallback behavior change, which affects source_app/destination_app attribution in telemetry.

- Signals: Envoy 1.40 EOL 2027-10-13
- Platform/SRE — Plan: v1.40.0 changes mcp_router to stop forwarding downstream headers (including
authorization) to backends by default — a silent auth-breakage risk on upgrade. Audit MCP router configs and validate header_forwarding settings before rolling this out to any cluster. - CI/CD — Skip

- Platform/SRE — Plan: Upgrade Envoy 1.38.x to 1.38.7 this quarter: it fixes a non-KEV/EPSS-0.00 CVE in wasmtime, several worker-thread race conditions during RDS route-config updates, and a 1.38.0-introduced regression that underreported Prometheus native histogram quantiles. No hard deadline; 1.38 EOL is 2027-04-23.

- Platform/SRE — Plan: Two crash-inducing security fixes (GHSA-8vc2-jrm4-835w, GHSA-47vj-9r25-wv5j) affect Envoy’s oauth2 and api_key_auth filters when handling CONNECT requests; no KEV listing or active exploitation reported, so schedule an upgrade to 1.38.6 this sprint if either filter is in use.

- Platform/SRE — Plan: Patch Envoy to 1.37.9 this quarter to resolve CVE-2026-54786 (not KEV-listed, EPSS 0.00) and three worker-thread race conditions in AWS request signing, local rate limiting, and SDS secret handling that could cause instability under RDS route updates; no forced deadline, 1.37 EOL is 2027-01-13.

- Signals: Envoy 1.37 EOL 2027-01-13 · CVE-2026-54786 — CISA KEV: not listed, EPSS 0.00
- Platform/SRE — Plan: Two GHSA-classified crash vulnerabilities in Envoy’s oauth2 and api_key_auth filters can be triggered by CONNECT requests; no KEV listing or active exploitation reported, but any team running these filters in production should schedule an upgrade to v1.37.8 this sprint. Envoy 1.37 EOL is 2027-01-13, so the branch is still supported.

- Platform/SRE — Learn: Meshery’s CNCF incubating status signals growing ecosystem legitimacy as a unified cloud-native management plane — worth evaluating if you manage multiple meshes or need a consolidated control surface, but no operational change required today.
- CI/CD — Skip
- Leader — Learn: CNCF incubating status reduces vendor-risk concerns around Meshery and may inform future golden-path decisions for mesh management, but no strategic decision is required now.
- Platform/SRE — Plan: A new Istio minor release is always a candidate for upgrade planning — review the full release notes for breaking changes, API removals, or deprecations before scheduling a mesh upgrade this quarter.

- 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.

- 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.

- 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.
