 ## Security
+* Upgrade google.golang.org/grpc to v1.82.1 to address `GO-2026-6061 <https://pkg.go.dev/vuln/GO-2026-6061>`_ (vulnerabilities in the HTTP/2 transport server implementation and the xDS RBAC authorization engine).
 * #4420: Harden the strict-mode HTTP client against SSRF. In strict mode the client now refuses at connect time to reach non-public addresses (loopback, private/RFC1918, unique local, link-local and unspecified), checked against the resolved IP so DNS-rebinding cannot bypass it, and refuses to follow a redirect that downgrades from HTTPS to HTTP. Cloud provider metadata endpoints are always blocked, following the OWASP SSRF prevention cheat sheet. Deployments that legitimately reach a private address for an internal flow (such as an internal credential offering or OAuth user flow) can permit specific ranges with ``http.client.allowedinternalcidrs``; publicly routable ranges that are internal-only can additionally be blocked with ``http.client.deniedcidrs``, which takes precedence. See :ref:`Outbound HTTP and SSRF protection <ssrf-protection>` for deployment guidance. Reported by @raysabee, fixed by @stevenvegt in https://github.com/nuts-foundation/nuts-node/pull/4420
 * #4421: Stop reflecting fetched HTTP response bodies in API responses. The OAuth2 and OpenID4VCI callback handlers no longer place a remote endpoint's response body or error text into the returned ``error_description``, the did:web resolver no longer returns the fetched document body in its parse error, and the Discovery Service client no longer includes the remote server's error response in errors returned through the discovery APIs. Such content is now logged (truncated) for diagnostics instead. Static context such as the endpoint that failed is retained. By @stevenvegt in https://github.com/nuts-foundation/nuts-node/pull/4421
 * Upgrade go.opentelemetry.io/otel to v1.44.0 to address `GO-2026-5158 <https://pkg.go.dev/vuln/GO-2026-5158>`_ (baggage header parsing did not cap raw header length, allowing denial-of-service through excessively large headers).
