This commit updates the O-RAN Cloud Notification API specification (oran.md)
to include comprehensive authentication and security documentation:
Authentication Mechanisms:
- Added new Chapter 4: Authentication and Security
- Documented mTLS (Mutual TLS) authentication at transport layer
- Documented OAuth 2.0 authentication at application layer
- Described dual authentication approach (mTLS + OAuth)
Security Features:
- Certificate-based client authentication (X.509)
- Bearer token authentication (JWT - JSON Web Tokens)
- Support for OpenShift OAuth and Kubernetes ServiceAccount tokens
- Token validation: issuer, audience, signature, expiration, scopes
- Certificate verification against trusted CA
- OpenShift Service CA integration
Authentication Requirements:
- Added authentication requirements table by endpoint and HTTP method
- POST /subscriptions: requires authentication (mTLS and/or OAuth)
- DELETE /subscriptions: requires authentication
- DELETE /subscriptions/{id}: requires authentication
- GET endpoints: public (no authentication required)
- /health endpoint: always public
Response Codes:
- Added 401 Unauthorized responses to POST and DELETE operations
- Updated response code descriptions with authentication details
- Clarified error scenarios for failed authentication
Security Considerations:
- Certificate management best practices
- Token management and lifecycle
- RBAC integration with Kubernetes ServiceAccount tokens
- Localhost exception for Helper/Sidecar containers
- Defense-in-depth security model
Configuration Examples:
- mTLS client certificate authentication example
- OAuth 2.0 Bearer token authentication example
- Dual authentication (mTLS + OAuth) example
- curl command examples for all authentication scenarios
Updated Documentation:
- Enhanced Authorization header description with OAuth details
- Added note about mTLS certificate verification at TLS layer
- Updated Table of Contents with new authentication chapter
- Maintained O-RAN specification formatting and structure
This update aligns the O-RAN specification with the implemented
authentication features in rest-api v2 and provides comprehensive
guidance for Event Consumers implementing secure API access.

Extend the WIP auth work to satisfy CNF-26787 and the related security bugs (OCPBUGS-116059/116202/116139/116791/116817): - Replace insecure JWT ParseUnverified (no signature check) with a TokenValidator interface. rest-api stays free of any Kubernetes client dependency; cloud-event-proxy supplies a TokenReview-based validator. Fail closed when OAuth is enabled but no validator is installed. Drop the golang-jwt dependency. - Apply authentication to ALL data endpoints (GET reads and CurrentState included), not just mutating ones. /health and / stay open for probes. - mTLS: use VerifyClientCertIfGiven so the trusted loopback fast-path (same-pod) still works while any presented certificate is verified against the CA pool; the middleware requires a verified certificate for all non-loopback requests. - Honor the centrally-managed TLS profile (CNF-21982): apply MinVersion and CipherSuites from AuthConfig instead of hardcoding TLS 1.2/defaults. - Remove InsecureSkipVerify on the endpoint-validation HTTPClient; verify against the CA pool. Add SSRF hardening (validateEndpointURI) on subscriber/publisher callback URIs, rejecting link-local, multicast, unspecified and cloud-metadata addresses.

Rename applyTLSProfile to ApplyTLSProfile so cloud-event-proxy's client config can apply the same centrally-managed TLS profile (min version and cipher suites) when building its mTLS client, keeping server and client TLS policy consistent per CNF-21982.

- Set an explicit TLS 1.2 floor on the endpoint-validation client and the mTLS listener config so gosec G402 is satisfied; ApplyTLSProfile still raises MinVersion to the cluster-configured floor. - Add isBlockedDialIP + newSafeDialContext: resolve the callback host and reject link-local, cloud-metadata, multicast and unspecified addresses before connecting (dialing the resolved IP closes the DNS-rebinding window). RFC1918/ULA and loopback stay allowed since consumers run as cluster Pods and RHT-0003 permits in-pod localhost callbacks. - Refuse to follow redirects during endpoint validation (CheckRedirect). - Add internal tests for the SSRF policy, loopback detection and TLS profile application.

- Around line 51-55: Update AUTHENTICATION.md so GET /subscriptions, GET
/subscriptions/{subscriptionId}, GET /publishers, GET /publishers/{publisherid},
and GET /{ResourceAddress}/CurrentState are listed as protected endpoints rather
than public, and revise the accompanying examples to show authentication
credentials.
- Around line 111-119: Update AUTHENTICATION.md, OPENSHIFT_AUTHENTICATION.md,
and README.md at the specified ranges and all related examples to match
AuthConfig: replace obsolete OAuth fields with requiredAudiences, state that
TokenValidator owns issuer, signature, expiration, and other token checks, and
remove claims that the library parses JWTs or validates issuers locally.
In `@examples/openshift-manifests.yaml`:
- Around line 79-87: Add a least-privilege ClusterRole granting
cloud-event-proxy-sa create access to authentication.k8s.io/tokenreviews, plus a
ClusterRoleBinding associating that role with the ServiceAccount. Inspect the
OAuth validator before adding any SubjectAccessReview permission, and include it
only if the validator actually uses that resource.
- Line 58: Update the AuthConfig manifest to use the supported requiredAudiences
field with https://kubernetes.default.svc, and remove the unsupported OAuth
issuer, JWKS, and scope fields. Ensure the resulting configuration supplies this
audience to TokenValidator.
- Around line 154-156: Add a Service CA-injected ConfigMap volume containing the
service-ca.crt key, and mount it at /etc/cloud-event-proxy/ca-bundle so
initMTLSCACertPool can load the intended CA bundle. Keep the existing
cloud-event-proxy-tls secret volume for TLS certificate and key material.
In `@v2/auth_internal_test.go`:
- Line 107: Update the three zero-value tls.Config expressions used by the
ApplyTLSProfile tests with narrow //nolint:gosec suppressions, including a brief
justification that the zero values are required to verify minimum-version
installation.
In `@v2/auth.go`:
- Around line 208-209: Update ApplyTLSProfile to reject TLS versions below TLS
1.2 for both server and client configurations, preserving TLS 1.2 as the minimum
regardless of the profile. Build the cipher lookup using only
tls.CipherSuites(), excluding tls.InsecureCipherSuites().
In `@v2/routes.go`:
- Line 81: Configure the rest client used before PostCloudEvent with
newSafeDialContext or an equivalent resolving dialer, rather than relying on the
default transport. Ensure hostname resolution is revalidated against blocked
addresses at connection time while preserving the existing validateEndpointURI
check.
- Around line 81-85: Update restclient.New to configure its http.Client
CheckRedirect callback to return http.ErrUseLastResponse, matching the redirect
rejection already used by s.HTTPClient in both configuration branches. Apply
this root-cause fix for the affected call paths at v2/routes.go lines 81-85 and
207-211; no direct changes are needed at those route validation sites.
In `@v2/server.go`:
- Around line 312-314: Update InitServer’s initMTLSCACertPool error path to
return the initialization error or otherwise prevent Start from marking the
server started; do not continue configuring RootCAs or ClientCAs with a nil pool
after failure, while preserving normal startup when CA initialization succeeds.
- Line 379: Remove InsecureSkipVerify from the TLS configuration used by the
health client for EndPointHealthChk, and ensure the localhost health-check
certificate includes localhost as a SAN so normal certificate-chain and hostname
verification remains enabled.
In `@v2/swagger.json`:
- Line 30: Update the Swagger authentication contract: replace the incorrect
basic scheme with mutual TLS support or the selected tooling’s vendor extension,
restrict authenticated traffic schemes to https, and add the required security
declarations plus 401 responses to both protected GET subscription operations
wrapped by applyAuth(..., true).
- Around line 26-27: Update the server configuration and startup flow so any
deployment with EnableOAuth enabled requires TLS, rejecting configurations where
EnableOAuth is true and EnableMTLS is false instead of calling ListenAndServe.
Update the OpenAPI scheme declaration in v2/swagger.json to advertise only
HTTPS, while preserving non-OAuth behavior.

The GetCurrentState tests reuse the server's outbound endpoint-validation
HTTPClient, which now enforces a no-redirect policy (SSRF safeguard). Those
tests built the request URL as apPath + "/"-prefixed resource, yielding a
double slash (".../v2//east-edge-...") that gorilla/mux answers with a 301
to the cleaned path. The old default client silently followed the redirect;
the hardened client returns the 301 unfollowed, so the tests saw an empty
body / wrong status.
Strip the leading slash so the URL is well-formed (single slash) and the
request reaches the handler directly, as a real O-RAN consumer would. No
production behavior change; the SSRF no-redirect safeguard stays intact.

The mTLS ApplyTLSProfile floor and the health-check InsecureSkipVerify are intentionally unchanged (central TLS profile adherence per CNF-21982/21769/22665 and in-pod loopback health checks, respectively).

The base-path route (api.HandleFunc("/", ...)) echoed the raw *http.Request
back to the caller via fmt.Fprintln(w, r). It was debug scaffolding from the
original v2 API commit: no callers, tests, docs, or swagger operations
reference it, and the health probe uses /health rather than the base path.
It also reflected caller-supplied request contents back unauthenticated,
which serves no purpose. Removing it; GET on the base path now returns 404.

The HTTP server only set ReadHeaderTimeout, leaving slow/stalled clients and
idle keep-alive connections unbounded. Add:
- WriteTimeout (30s): caps request-body read + response write; set above the
10s outbound initial-notification POST performed during createSubscription.
- IdleTimeout (60s): bounds retention of idle keep-alive connections so a
connection-hoarding flood cannot exhaust the listener.
- MaxHeaderBytes (1 MiB): caps per-connection header memory.
Defense-in-depth against connection-exhaustion DoS on the port; behavior for
normal (small, fast) API traffic is unchanged.

Add ReadTimeout to the HTTP server. ReadHeaderTimeout only covers header reads and WriteTimeout does not bound request-body reads, so a client could dribble a POST body to pin a handler goroutine indefinitely (Slowloris on the request body, CWE-400). Request bodies are small JSON documents, so the read deadline is set to the same generous ceiling as the write side. Clarify the swagger BearerToken definition to state the security requirements are configuration-dependent: the Bearer token is required only when OAuth is enabled and mTLS only when mTLS is enabled, and loopback requests bypass both. Swagger 2.0 cannot express conditional security, so this is documented in the definition description.

The server acts as an HTTP client for two outbound POSTs while handling a request: the subscription initial-notification push and the publisher endpoint-validation probe. When the callback endpoint enforces mTLS and/or OAuth, these pushes previously failed: - No client certificate was presented. The server's own serving certificate is serverAuth-only and cannot be reused as a client cert, so an mTLS-enforcing callback rejected the push with "client certificate required". Add ClientCertPath/ClientKeyPath to AuthConfig and load the keypair into the push client's tls.Config.Certificates. - No bearer token was attached. Wrap the push transport in a bearerTokenRoundTripper that injects the client's ServiceAccount token, re-read per request so rotated projected tokens stay current, when OAuth is enabled. Also skip the publisher endpoint-validation probe for loopback endpointURIs: the ptp plugin self-registers publishers against localhost, but the Service-CA serving cert only carries *.svc SANs so an https://localhost probe can never pass hostname verification. Loopback callers are already trusted via the auth loopback fast-path; the static SSRF checks still apply. Covered by a new bearerTokenRoundTripper unit test (header injection, token rotation re-read, missing-token graceful passthrough, request-clone contract).

The server is an mTLS/OAuth client on the push leg: when a subscription is created it pushes the initial notification to the subscriber callback. Document how that push authenticates - the optional clientAuth keypair (ClientCertPath/ClientKeyPath, since the Service CA serving cert is serverAuth-only), the per-request bearer token, and the dual-purpose CACertPath used as RootCAs to verify the consumer's server cert - plus the OVN-Kubernetes join-subnet NetworkPolicy caveat for hostNetwork publishers.

A subscriber may register an http:// EndpointUri and the token is a cluster credential, so it must never traverse plaintext; plain-http pushes are sent unmodified and the callback enforces its own auth. - server.go: wire the bearer-token RoundTripper independently of mTLS so an OAuth-only configuration (no EnableMTLS) still authenticates its pushes; previously the wrapper was only installed in the mTLS branch. - auth_internal_test.go: rename the `cap` local that shadowed the builtin (revive) and close each response body (bodyclose) to fix the Linting job; add a case asserting no Authorization header is sent over plaintext http. - AUTHENTICATION.md: document the https-only token behavior and OAuth-only push support.

Follow-up to the push-leg review fixes so the Linting job passes: - auth.go/server.go: extract the repeated "https" scheme literal into a schemeHTTPS constant (goconst). - auth_internal_test.go: reuse the function-scoped err instead of redeclaring it in the rotated-token and plaintext-http blocks (govet shadow). Verified with golangci-lint v1.64.8 (the CI version): clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Signed-off-by: Jack Ding <jackding@gmail.com>

Summary
Enforce mTLS + OAuth authentication on all exposed O-RAN ocloudNotifications v2 REST APIs, implementing CNF-26787. This supersedes the WIP #109, which only protected the mutating endpoints.
Based on O-RAN CR RHT-2025.05.13-O-RAN-CR-0003 "Remove Localhost Constraints".
