Purpose

The Test page could only build a cURL command, there was no way to actually send a request from the portal. Having the browser call the gateway directly doesn't work in practice, for three independent reasons:

  • The gateway is a different origin in every deployment, so the test-key header triggers a CORS preflight that only succeeds if the API happens to carry a cors policy.
  • A plain-http gateway is blocked as mixed content from an https portal.
  • A cluster-internal gateway isn't routable from the user's machine at all.

So the console needs a server-side relay. That relay dials an address derived from tenant-controlled data, which makes it an SSRF surface that has to be bounded deliberately.

Resolves https://github.com/wso2-enterprise/apim-product-management/issues/505, https://github.com/wso2-enterprise/apim-product-management/issues/459

Goals

  1. An interactive Swagger console on the Test page that can actually send requests.
  2. Requests relayed through the BFF by default, removing all three failure modes above.
  3. A Direct escape hatch for the inverse case, a self-hosted gateway the browser can reach but the BFF cannot.
  4. A bounded, operator-configurable egress policy so the relay can't be aimed at arbitrary in-cluster services.

Approach

UI

The Test page gains a Console / cURL view switch. The Console view mounts TestConsoleSpecViewer — a sibling of the existing SwaggerSpecViewer, not a change to it, since that component is mounted by two already-shipped pages.

The spec's servers entry is rewritten to the selected gateway's invoke URL (withServerUrl), and a requestInterceptor injects the test key as a header or query parameter per the API's api-key-auth policy. So the request Swagger builds, displays, and puts in its curl snippet is the real gateway call.

The Through proxy / Direct switch sits in the Gateway card, Console view only; a copied cURL command leaves from the user's own terminal, so neither mode applies to it. The choice persists in localStorage, because it tracks where the user's browser sits relative to the gateway, not anything about the API.

Direct mode is the absence of a transport override, not a second one:

contextRef.current.mode === 'direct'
  ? oriAction(payload)                   // swagger-client falls back to global fetch
  : oriAction({ ...payload, userFetch }) // relay installed

swagger-client calls request.userFetch || fetch, so omitting the key is what sends the browser straight at the gateway. The mode is read per Execute rather than captured — swagger-ui-react keeps only the first plugins value it is given.

BFF

Design Doc for the BFF proxy: Link

One endpoint: POST /api/test-console/invoke. The browser posts a JSON envelope and gets one back; it never names a URL.

envelope → session check → resolve target → sanitize → egress check → dial → response
  1. Resolve (internal/testproxy/resolve.go) — the browser names (orgHandle, restApiId, gatewayId). The BFF asks Platform API with the caller's own token, so entitlement is Platform API's decision, not re-implemented here. The gateway must be one the API is actually deployed to. Results are cached on a digest of the token, so one caller's resolution can't serve another.
  2. Sanitize (sanitize.go) — method allowlisted (no CONNECT/TRACE), CR/LF/NUL rejected, path containment checked on the decoded path, and Cookie / Host / hop-by-hop / X-Forwarded-* refused from the caller.
  3. Relay (client.go) — this package never receives the session token, so it is structurally incapable of leaking it to a tenant-controlled gateway. Headers are assigned, not merged. Redirects are never followed. Bounded pool with a bounded queue; oversized responses truncate rather than fail.
  4. Respond — always inert application/json. A gateway's Set-Cookie and Content-Type travel as JSON string data, never as headers on the portal origin.

HTTP status is never overloaded: a gateway that answered at all is a successful relay (200, with its status inside). Only the relay's own failures carry an error status (TARGET_NOT_ALLOWED 403, RELAY_BUSY 503, UPSTREAM_TIMEOUT 504, UPSTREAM_UNREACHABLE 502, …).

Egress policy

New internal/egress package. Two rules only:

  1. deny always wins.
  2. allow narrows when set, and is ignored when empty.
[api_control_plane.test_console.egress]
# allow_hosts = ["gw.api.example.com", "*.gw.svc.cluster.local"]
# allow_cidrs = ["10.42.0.0/16"]
# allow_ports = [443, 8443, 9443]
# deny        = ["10.42.9.0/24", "private"]   # CIDRs and/or private|loopback|cgnat

There is deliberately no setting that re-opens something deny closed — netguard's widening AllowCIDRs field is never populated by this package, so the "a carve-out re-opened the metadata endpoint" class is unrepresentable rather than merely guarded against. Link-local/metadata, unspecified, multicast and the IPv4-translating IPv6 ranges (6to4, NAT64) are refused unconditionally.

Host and port are checked at resolution — neither depends on DNS, so a refusal is a specific 403 with the reason logged rather than a vague 502. Addresses are checked inside the dial, which resolves and connects in one step to close DNS rebinding. The categorical checks are delegated to netguard.Validate per resolved address rather than restated, so there is one implementation. httpkit is unmodified.

User stories

  • As an API developer, I can send a request to a deployed gateway from the Test page and see the full response, including headers a browser could not read cross-origin.
  • As an API developer testing a secured API, the test key is attached automatically, in whichever position the api-key-auth policy specifies.
  • As a user whose gateway is self-hosted and unreachable from the portal server, I can switch to Direct and have the browser call it, accepting that the API then needs its own cors policy.
  • As an operator, I can state where my gateways live (allow_hosts / allow_cidrs / allow_ports) and the relay cannot be aimed anywhere else.

Documentation

  • portals/api-control-plane/bff/internal/egress/README.md - the egress model, decision order, startup failures, worked examples (new, in this PR).
  • portals/api-control-plane/configs/config.toml - every key documented inline with its default and rationale.

Automation tests

  • Unit tests
    • BFF: 74 Go test functions across testproxy (sanitizer, resolver, relay bounds, truncation, header forwarding), egress (narrowing vs. deny precedence, group expansion, host/port matching, startup refusals) and server (status contract, response inertness, CSRF, session).
    • UI: 106 test cases across TestPage, TestConsoleSpecViewer, proxyTransport, callMode, specServers, filterSpec, swaggerRequest.
    • Both suites pass; go vet and eslint clean.
  • Integration tests
    • None added. The relay's end-to-end path is covered at the HTTP boundary in internal/server/testconsole_test.go, which drives a real httptest BFF against a stub Platform API and a stub gateway — including the egress refusal paths and the "every constraint satisfied" success path.

Security checks

  • Followed secure coding standards in http://wso2.com/technical-reports/wso2-secure-engineering-guidelines? yes
  • Ran FindSecurityBugs plugin and verified report? N/A — FindSecurityBugs is a Java static-analysis plugin and this change is Go + TypeScript. go vet, eslint and the repo's own .claude/rules (SSRF, file access, error handling, output encoding) were applied instead.
  • Confirmed that this PR doesn't commit any keys, passwords, tokens, usernames, or other secrets? yes

Merge Risk: 🔵 Low · up to 5a63c

Some failed console requests can show a misleading refusal or an unformatted error. These bounded issues should be fixed or accepted before merging.

Security Architecture Review

Security architecture risk: 🟠 High · up to 5a63c

The console can now send requests from the server’s network. Destination restrictions are optional by default, so tenant-managed gateway addresses may expose internal services beyond the intended gateways. Authorization checks and credential isolation reduce risk, but do not replace network containment. Request processing also begins before capacity limits apply.

Retained concerns

  • High · security · inferred: The default-enabled relay does not require gateway-specific destination restrictions. Its default policy permits private, loopback, and CGNAT destinations on unrestricted ports. An actor able to influence an eligible gateway endpoint or its DNS could consequently direct authenticated console requests toward non-gateway services reachable from the server, potentially crossing tenant or infrastructure boundaries. Server-side gateway selection, deployment checks, path containment, and metadata-address blocking constrain this path but do not establish that a registered endpoint is an approved network destination. Actual exploitation depends on registration controls, deployment authority, and network topology that were not established.
  • Medium · security · inferred: The new handler buffers each request envelope and resolves its target before acquiring relay capacity. Concurrent cache misses can retain request data and issue Platform API reads even when the relay’s running and pending limits are exhausted; invalid gateway selections are also resolved before rejection. Individual byte limits, caching, and the resolution timeout constrain each request, but not aggregate work in this phase. This new buffered workflow can weaken denial-of-service containment for the shared portal and authorization service. Deployment-level throttling was not established.
Security review details

Security Blast Radius

  • inferred — The maximum plausible network exposure is HTTP(S) services reachable from the BFF, including loopback and private infrastructure beyond the caller’s tenant. Exploitation requires an eligible gateway whose endpoint or DNS the actor can influence, plus console access to its API. The inspected code does not grant cloud or service credentials to the request; sensitive outcomes would depend on downstream authentication, source-network trust, and reachable services.

Security Findings and Attack Paths

  • inferred — No verified Security finding is retained in the canonical brief. The architecture attack path is tenant-influenced gateway address to authorized resolution to default-permitted internal dialing. It does not require supplying an absolute URL in the browser envelope or bypassing DNS validation. Production registration controls and exact endpoint-management privileges remain unresolved, so this is an inferred concern rather than a verified arbitrary-target exploit.

Trust Boundaries and Controls

  • observed — The invoke route is covered by the custom-header CSRF check and independently rejects missing or expired sessions. Resolution delegates API entitlement to Platform API using the caller’s token; gateway selection requires deployment and rejects conflicting nonempty organization IDs. Gateway requests exclude cookies, forwarding headers, and session credentials, and redirects are not followed. Production enforcement for omitted or browser-selected organization identifiers was not established.
  • observed — The egress policy validates every resolved address before dialing an approved IP directly, closing the check-to-connect DNS-rebinding window. Operator allow lists narrow policy without reopening denied addresses. Link-local, unspecified, multicast/broadcast, and the explicitly listed IPv4-translating prefixes remain blocked even when allow lists are configured.

Resilience and Maintainability Implications

  • observed — Capacity accounting and cleanup protect the admitted relay phase, but resolution precedes that boundary. Cache hits avoid upstream reads; cache misses perform sequential API and gateway reads without that admission limit. The inspected server and shared Platform API transport supply timeouts, not an independent concurrent-work ceiling. Their unchanged limits predate this PR; the new buffered resolution workflow is the additional exposure.

Hardening Proposals

  • proposed — Require an explicit gateway egress profile before enabling the relay in production, including approved destinations and ports and a loopback denial unless deliberately needed. Complement application controls with network isolation so endpoint-management authority cannot imply access to unrelated infrastructure.
  • proposed — Apply bounded admission before envelope buffering and target resolution, or give that phase a separate bounded pool. Preserve cancellation cleanup and add appropriate caller fairness so one session cannot monopolize shared resolution and relay capacity.

297-311: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Make each case in TestNewRelayRejectsUnboundedOptions violate exactly one bound.

Every case leaves MaxRequestBytes at zero and Egress at nil. NewRelay therefore fails every case for the same reason. If someone removes the RequestTimeout, MaxResponseBytes, or MaxConcurrent check, the test still passes. Start each case from a fully valid RelayOptions, including a parsed policy, and zero one field.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Return a timeout when target resolution reaches its deadline.

If the Platform API does not finish within testResolveTimeout, Resolve returns an error. The error branch then returns 403 TARGET_NOT_ALLOWED. The console reports a target-policy refusal for a transient timeout. Check resolveCtx.Err() before the policy-error response and return a timeout response when the deadline expired.

Validate relay header entries before converting the response.

If a successful relay reply contains headers: [null], isRelayResult accepts it because it checks only that headers is an array. toResponseLike then throws a TypeError while destructuring the entry, before its try block. Check that every entry has string name and value fields, and add a relay-response test for this case.

🐛 Suggested fix
-  return typeof status === 'number' && Array.isArray(headers);
+  return (
+    typeof status === 'number' &&
+    Array.isArray(headers) &&
+    headers.every(
+      (header) =>
+        typeof header === 'object' &&
+        header !== null &&
+        typeof header.name === 'string' &&
+        typeof header.value === 'string',
+    )
+  );
