Purpose

Two changes on the API Portal that support Platform API's outbound publish path and align existing IDP-login handling with the JWKS URL the deployment is already configured with.

  1. Platform API needs a service identity when it publishes APIs, MCP servers, their content, and subscription plans to this portal. Reusing dp_admin would grant it far more than it needs (organization settings, applications, subscriptions, webhooks, key managers). A narrower service role scoped to just the artifacts Platform API produces keeps the grant surface small.
  2. The passport-oauth2 login callback was calling safeDecodeJwt on the id_token and access_token — a plain base64 decode, no JWKS verification. The rest of the auth stack (authMiddleware.js, tokenUtil.js) already verifies bearer tokens against config.auth.idp.jwksUrl. This PR wires the login callback to that same URL so signature / iss / aud / exp checks apply at login too.

Goals

  • Introduce a platform-api-system role in role-to-scope-mapping.yaml with the five dp:*:manage scopes Platform API needs to publish content into the portal.
  • Replace safeDecodeJwt in the passport-oauth2 verify callback with jose.jwtVerify against the JWKS URL already configured for the IDP.
  • Update the two role-count assertions in the config test suite that hard-coded 4 roles to 5 roles, and add unit tests for the pre-existing platformJwt verify/decode helpers.

Approach

Role additionportals/api-portal/resources/role-to-scope-mapping.yaml:

  • New entry platform-api-system with dp:api:manage, dp:api_content:manage, dp:mcp_server:manage, dp:mcp_server_content:manage, dp:subscription_plan:manage.
  • Strict subset of dp_admin — no organization, application, subscription, webhook_subscriber, or key_manager scopes.
  • Not aliased and not mapped to either page-access tier: this is a service identity, not a browsing role.

Login-callback verificationportals/api-portal/src/middlewares/passportConfig.js:

  • New verifyIdpJwt(token, audience) helper. Uses jose.createRemoteJWKSet(new URL(config.auth.idp.jwksUrl)) and jose.jwtVerify with algorithms: constants.JWT_ASYMMETRIC_ALGORITHMS, plus issuer when configured. Audience is passed per token type by the caller.
  • Passport verify callback now:
    • id_tokenverifyIdpJwt(params.id_token, config.auth.idp?.clientId) — audience is the client_id per OIDC Core §3.1.3.7.
    • access_tokenverifyIdpJwt(accessToken, config.auth.idp?.audience) — audience uses auth.idp.audience when configured; skipped otherwise since aud on access tokens varies by IDP. Signature / iss / exp still run.
    • Verification failure surfaces as done(err) — the callback no longer falls through with empty claims when a token fails to decode.
  • Uses the JWKS URL, issuer, and audience fields that already exist in the config schema — no new keys.

Tests:

  • authorizationConfig.test.jsrole mode with the shipped mapping starts and loads its ___ roles — expected count 4 → 5.
  • roleScopeMap.test.jsthe shipped role-to-scope-mapping.yaml validates against the shipped OpenAPI spec — expected keys list gains 'platform-api-system'.
  • New platformJwt.test.js — 8 node:test cases for verifyPlatformJwtClaims and decodePlatformJwtClaims (signature match, wrong-key rejection, expired-token rejection, malformed input, missing key file, empty scope claim, decode-without-verify, decode malformed).

User stories

  • As a Platform API operator, I want a narrow service role for the portal so outbound publish calls don't run with organization-admin privileges.
  • As an API Portal operator, I want the login callback to apply the same JWKS verification that the REST bearer-token path already applies.

Documentation

N/A — role naming, scope grants, and IDP config keys are documented in the YAML file and configLoader; both already carry inline documentation and this PR extends both in-place.

Automation tests

  • Unit tests
    • portals/api-portal/src/utils/platformJwt.test.js — 8 new tests exercising the platform JWT verify/decode helpers end-to-end with jose.generateKeyPair / jose.SignJWT.
    • portals/api-portal/src/config/authorizationConfig.test.js — updated role-count assertion; the surrounding suite exercises configLoader validation of the shipped mapping.
    • portals/api-portal/src/config/roleScopeMap.test.js — updated shipped-keys assertion; the surrounding suite exercises grant-table validation.
  • Integration tests
    • N/A — this PR adds no request-path code beyond the OAuth2 callback, which is exercised via the existing IDP-mode flow.

Pull request overview

This PR updates the API Portal to (1) introduce a narrow service role for Platform API outbound publishing, and (2) ensure the OAuth2 login callback verifies IDP tokens using the configured JWKS (aligning login-time validation with existing bearer-token validation).

Changes:

  • Added platform-api-system role to the shipped role-to-scope mapping with only the dp:*:manage scopes needed for outbound publish artifacts.
  • Replaced non-verifying JWT decode in the passport-oauth2 verify callback with jose.jwtVerify against the configured IDP JWKS (with issuer/audience enforcement as configured).
  • Updated config/role-mapping tests for the new role and added unit tests for existing Platform JWT verify/decode helpers.

Five follow-ups from CodeRabbit + Copilot review of the previous commits:

1. Cache JWKS resolver at module scope, keyed by URL. createRemoteJWKSet
   keeps an internal key cache and rate-limits refreshes; recreating it
   on every verifyIdpJwt call (twice per login) threw that state away
   and pushed the JWKS endpoint on every login.

2. Fail closed in verifyIdpJwt when the token argument is falsy. The
   helper previously returned {} on a missing token, which let the
   OAuth2 callback continue with empty claims and land the user in a
   session that 403'd on every subsequent request. The docstring already
   said "throws when checks fail" — this makes the code match.

3. Return a generic error to Passport (Login failed: token verification
   error) and keep the underlying jose message in the log. Depending on
   how the callback route renders the error, the raw message could leak
   JWKS URL parse failures, network errors, etc. to the browser.

4. Require auth.idp.jwks_url in configLoader when auth.mode = "idp".
   Both the login callback (passportConfig.js) and the REST bearer
   verifier (authMiddleware.js) already require it at request time;
   fail closed at startup instead of at first login.

5. Assert the shipped platform-api-system role's exact scope list in
   roleScopeMap.test.js (in addition to the role-name-only assertion).
   Pins the least-privilege contract so a silent scope widening or
   narrowing fails this test.

…/authConfig)

Adopts the shared-key auth model designed in the vault under
Projects/DevPortal Publishing/Platform-API-Devportal-Design/SharedKey-Auth-Design.md.
Platform-API now stores an encrypted raw shared key per portal and (in a
follow-up) sends it as `Authorization: SharedKey <raw>` on outbound
publishing calls. The devportal side of this landed on
`feat/api-portal-role-scope-and-auth-fixes` (PR wso2#3243).

- Schema (all 3 engines): drop `auth_type` + `auth_configuration`, add
  `internal_auth_key BYTEA NOT NULL`. `metadata` unchanged.
- Model: drop `AuthType` + `AuthConfig`; add `InternalAuthKey []byte`
  (tagged `json:"-"` so it's never marshalled).
- Constants: remove `APIPortalAuthType*` / `APIPortalAuthConfig*`; add
  `APIPortalSharedKeyAuthScheme = "SharedKey"` and
  `APIPortalSharedKeyHexLength = 64`.
- Repository: scan/insert/update rewritten for the new column set.
- Service: drop authType/authConfig validation + oauth2 secret encryption;
  add `validateAndEncryptSharedKey` (64-char hex format check + AES-GCM
  via the existing vault). Create requires `sharedKey`; Update treats it
  as optional rotation.
- Translate: drop authConfig struct/map helpers;
  `ModelToAPIPortalResponse` and `modelToAPIPortalListItem` no longer
  emit `authType` / `authConfig`.
- OpenAPI: drop `authType` / `authConfig` from all Portal schemas;
  delete `ApiPortalAuthConfig`; add `sharedKey` (writeOnly,
  `^[0-9a-fA-F]{64}$`) to Create (required) + Update (optional).
  `api/generated.go` regenerated.
- `api_portal_auth.go`: stubbed to a minimal `AuthProvider` interface +
  `APIPortalAuthRegistry` (Invalidate/Get). Real SharedKeyAuthProvider
  lands in a follow-up along with the rewritten tests.

The four existing `_test.go` files (repository / service / handler
integration / auth) were removed here; they were tightly coupled to the
old shape (~1700 lines of assertions on `AuthType`/`AuthConfig` fields
and `clientSecret` encryption) and will be rewritten in the follow-up
alongside the SharedKey provider.

Build + vet clean; unrelated package tests unaffected.

Replaces the earlier stub that returned "not yet implemented" from
APIPortalAuthRegistry.Get. Platform-API's outbound publisher now has
a real path to obtain the Authorization header for a portal:

  hdr, err := apiPortalService.AuthHeaderForPortal(ctx, handle, orgID)
  // hdr == "SharedKey <raw>"

Companion side of the shared-key mechanism landed on:
  - wso2#3243        devportal middleware + config +
                                    setup.sh (raw generation)
  - wso2-enterprise/apim-saas#2957 cloud plugin (raw generation on
                                    create + hash into OpenBao)
  - wso2-enterprise/wso2cloud#995  RT template (hash projected into
                                    portal pod)

- internal/service/api_portal_auth.go — full rewrite
  - sharedKeyAuthProvider: decrypts the row's internal_auth_key ONCE
    at construction (via vault.SecretVault), holds the "SharedKey
    <raw>" header string, returns it on every AuthorizationHeader.
    No per-call decrypt cost, no per-provider mutex on the hot path.
  - NewSharedKeyAuthProvider(vault, encryptedKey) constructor with
    input validation (non-nil vault, non-empty ciphertext).
  - APIPortalAuthRegistry now takes portalRepo + vault. Get(handle,
    orgID) misses the cache -> loads row via
    portalRepo.GetByHandleAndOrgID -> constructs provider ->
    caches under registryKey(orgID, handle). Double-check pattern
    under mutex so concurrent Gets for the same key resolve to a
    single stored instance (a lost race just discards one
    just-constructed provider, no correctness impact).
  - registryKey = orgID + "/" + handle so the same handle in two
    orgs never cross-contaminates.
  - Invalidate(handle, orgID) drops the cached entry — idempotent,
    safe from Delete paths.

- internal/service/api_portal.go
  - invalidateCachedAuthProvider now takes (handle, orgID); the
    two callers (Update + Delete) pass portal.OrganizationID.
  - AuthHeaderForPortal(ctx, handle, orgID) — the one-line surface
    the future publisher code calls. Wraps registry.Get +
    provider.AuthorizationHeader. Returns APIPortalNotFound for
    unknown portals, plain errors on decryption / config problems
    (permanent failures — callers should not retry).

- internal/server/server.go
  - NewAPIPortalAuthRegistry() now takes apiPortalRepo + secretVault
    (the two deps already in scope on either side of the call).

Build + vet + non-disabled tests all pass in both platform-api and
the apim-saas plugin that symlinks into it.

dushaniw and others added 7 commits September 11, 2026 13:13
Platform API mints an outbound token carrying roles=["platform-api-system"]
when it calls the portal's admin REST to publish APIs, MCP servers, their
content, and subscription plans. In role-authorization mode (the default),
the portal looks that role up in this file and expands to the corresponding
dp:* scopes. Without an entry the token authenticates but the request is
denied for lack of scopes.

The role is added as a distinct entry rather than a dp_admin alias: it's a
service identity (not a human persona) and its grant is a strict subset of
dp_admin's — publishing scopes only, no access to organization settings,
applications, subscriptions, webhooks, or key managers.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The passport-oauth2 callback used safeDecodeJwt on the id_token and
access_token freshly returned by the IDP. safeDecodeJwt reads the
payload without any signature, issuer, audience, or expiry checks — so
a tampered token or one issued for a different audience by the same
IDP would still be accepted as the login identity.

Replace with a verifyIdpJwt helper that uses jose's jwtVerify against
the same JWKS URL the OAuth strategy is already configured with:
  - id_token audience defaults to auth.idp.clientId (OIDC Core §3.1.3.7).
  - access_token audience uses auth.idp.audience when configured;
    otherwise aud validation is skipped for the access token while
    signature / issuer / expiry checks still run.
  - Verification failure surfaces as a login failure (done(err)) rather
    than a silently-accepted forged token.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two assertions hard-coded the shipped role-to-scope-mapping.yaml's
role count. Adding platform-api-system flips 4 → 5 in both places.
Covers verifyPlatformJwtClaims (signature match, wrong-key rejection,
expired-token rejection, malformed input, missing key file, empty-scope
handling) and decodePlatformJwtClaims (parses without verifying,
returns null for malformed input). Uses node:test and jose helpers to
build tokens rather than relying on external fixtures.

Implements the API Portal side of the shared-key mechanism designed in
Projects/DevPortal Publishing/Platform-API-Devportal-Design/SharedKey-Auth-Design.md.
Platform-API's outbound publishing calls (publish/update/delete an API,
API content, MCP Server, MCP Server content, subscription plan) now
authenticate with `Authorization: SharedKey <raw>` - a custom auth
scheme (RFC 7235), not the OAuth 2.0 Bearer scheme. Devportal stores
only sha256(raw) and constant-time compares against the value in the
incoming header. Consumer login (portal UI) and existing OAuth REST
callers are untouched, shared-key is a strictly additive path.

Companion work on platform-api side lands on feat/api-portals-crud
(PR wso2#3219).

- New `[api_portal.internal_auth] hash` section in config.toml +
  config-template.toml; loaded via existing `{{ file "..." }}`
  interpolation into `config.internalAuth.hash`.
- `configDefaults.js`: `internalAuth: { hash: '' }` as the DEFAULTS
  entry; empty means feature disabled and every SharedKey request 401s.
- `configLoader.js`: fail-closed startup check enforcing the 64-char
  hex format when a hash is configured. Matches the existing pattern
  for `encryption_key` and `session_secret`.
- New `src/middlewares/sharedKeyAuth.js`: scheme parser +
  `verifyHash` (sha256 + `crypto.timingSafeEqual`) +
  `synthesiseSharedKeyPrincipal` (expands `platform-api-system` role
  through `roleScopeMap.expandRoles`, yielding the five `dp:*:manage`
  scopes and nothing else).
- `authMiddleware.js`: new case 0 in `authResolver` for SharedKey
  scheme, runs before session/bearer/mTLS. Verifies, resolves this
  portal's own org via `resolvePortalOrg`, sets `req.auth` with
  mode `'shared-key'`. Bad SharedKey values 401 immediately, no fall
  through. `OAuth2Security` now allows `mode === 'shared-key'` so its
  ordinary scope check runs against the synthesised scope list - this
  is what limits shared-key traffic to the 5 admin write operations
  without any hand-maintained per-handler wrap list.
- `csrfProtection.js`: bypass CSRF for `Authorization: SharedKey` the
  same way it does for `Bearer`. Non-browser client, no cookies.
- `portals/scripts/setup.sh`: new `--rotate-internal-key` flag +
  generation block after the session-secret block. First run creates
  a 256-bit raw key, writes sha256 hex to
  `resources/keys/api-portal-internal-key-hash` (container-readable)
  and raw to `resources/keys/api-portal-internal-key.raw` (mode 0600,
  host-owner only, one-time-read). Stdout emits only the file paths,
  never the raw value.

Tests (20 total, node:test + child-spawn pattern to work around
`configLoader.js`'s fail-closed module-load):
- `src/config/internalAuthConfig.test.js` (7): fail-closed startup
  checks - empty hash boots (feature disabled), valid 64-char hex
  boots, malformed refuses to start with actionable error message.
- `src/middlewares/sharedKeyAuth.test.js` (13):
  parseAuthorizationScheme, isSharedKeyRequest, verifyHash,
  synthesiseSharedKeyPrincipal, tryAuthenticate (all three tri-state
  outcomes plus the two "wrong scheme with hash-matching value" and
  "SharedKey with no configured hash" negative cases).

All 20 tests pass. Full suite: 130/136 pass, 6 pre-existing
better-sqlite3 native-binding failures unrelated to this change
(confirmed by re-running with these changes stashed).

Locks the exact set of OpenAPI operations a verified shared-key caller
can reach through the platform-api-system role. Silent-widening (a new
op that copy-pastes a dp:*:manage scope) and silent-narrowing (a scope
rename that drops an existing op out of reach) both trip the test now.
