Why

rocketadmin-saas is growing an email-confirmation gate (Site-Nova/sitenova#142): registration — and login of an unconfirmed user — issues a session carrying a new email_verify scope, and the account must be unusable until the code from the letter is entered.

That only holds if this service refuses the scope. A satellite cannot enforce a restriction on the core's own API, and neither can agents-core: both validate end-user cookies through POST /saas/user/validate-token here. Without this change the gate is decoration.

What

  • JwtScopesEnum gains EMAIL_VERIFY. This is what makes allowScopes able to name the scope. It is enum-validated (@IsIn(Object.values(JwtScopesEnum))), so until the value exists here, every satellite request asking to accept it is rejected by the ValidationPipe with a 400 before any handler runs:

    Property "allowScopes" validation failed with following errors:
    each value in allowScopes must be one of the following values: 2fa_enable
    

    That is the right failure — a core that cannot name a scope cannot enforce it either — but it makes this DTO a cross-repo contract, so validate-user-token-dto.test.ts now pins it. (This exact 400 is what turned the sitenova PR's saas-e2e red and sent me here.)

  • New EmailVerificationRequiredException — 400, internal code 1203 — mirroring TwoFaRequiredException, so a satellite can route on the reason instead of parsing a message.

  • One assertTokenScopeAllowed() replaces four copies of the includes(TWO_FA_ENABLE) check: auth.middleware, auth-with-api.middleware, public-or-auth.middleware, and ValidateUserTokenUseCase.

Behavior for existing tokens is unchanged

  • The three request middlewares stay strict — they accept no allowScopes, exactly as before.
  • ValidateUserTokenUseCase keeps its allow2faEnableScope semantics untouched, including the deliberate suspension-check skip that mirrors NonScopedAuthMiddleware.
  • An unrecognized scope is still ignored, preserving what the replaced checks did. Two reasons that matters: a token minted by a newer service must not lock a user out of an older one, and it is what keeps IMPERSONATED tokens working.

Deploy order

Ship this before or with the rocketadmin-saas change that starts issuing the scope. Merged early it is inert (nothing mints an email_verify token yet); merged late, unverified users sail straight through — and the satellite's verify/resend routes 400 with the message above.

Tests

126 unit tests pass (18 new), typecheck and Biome clean. All written before the code — I verified the DTO test catches the real break by reverting the enum value, which reproduces that CI failure in about a second instead of twelve minutes.

Summary by CodeRabbit

  • New Features
    • Added email-verification protection for restricted account actions.
    • Users with unconfirmed email addresses now receive a clear prompt to verify their email.
    • Added support for email-verification-restricted access tokens.
  • Bug Fixes
    • Standardized enforcement of two-factor authentication and email-verification requirements across authenticated and token-validation flows.
    • Improved compatibility with unrecognized token permissions, preventing unnecessary access blocks.
  • Tests
    • Added coverage for token permissions, verification requirements, validation errors, and permitted access scenarios.

…t the point

rocketadmin-saas is growing an email-confirmation gate: registration (and
login of an unconfirmed user) issues a session carrying a new 'email_verify'
scope, and the account must be unusable until the emailed code is entered.
That only holds if THIS service refuses the scope — a satellite cannot
enforce a restriction on the core's own API, and neither can agents-core.

- JwtScopesEnum gains EMAIL_VERIFY, so `allowScopes` (which is enum-validated)
  can name it. Until it exists here, every satellite request asking to accept
  it is rejected by the ValidationPipe with a 400 before any handler runs —
  correct, but it makes this a cross-repo contract: the scope has to land here
  first. `validate-user-token-dto.test.ts` pins that contract.
- new EmailVerificationRequiredException (400, internal code 1203), mirroring
  TwoFaRequiredException, so a satellite can route on the reason rather than
  parse a message.
- the four `includes(TWO_FA_ENABLE)` checks (three request middlewares plus
  ValidateUserTokenUseCase) become one `assertTokenScopeAllowed()`. Behavior
  for existing tokens is unchanged, including that an UNRECOGNIZED scope is
  still ignored — a token minted by a newer service must not lock a user out
  of an older one, and it is what keeps IMPERSONATED tokens working. The
  use case's allowScopes/suspension semantics are untouched.

Deploy this before (or with) the rocketadmin-saas change that starts issuing
the scope, or unverified users sail straight through.

Review Change Stack

📝 Walkthrough

Walkthrough

The change centralizes JWT scope validation, adds the EMAIL_VERIFY scope and its exception, and updates authentication middleware and token validation to enforce allowed scopes. Tests cover scope handling, DTO validation, exception details, and forward compatibility.

Changes

JWT scope authorization

Layer / File(s) Summary
Scope and exception contracts
backend/src/entities/user/enums/jwt-scopes.enum.ts, backend/src/exceptions/...
Adds EMAIL_VERIFY, its internal error code, message, and EmailVerificationRequiredException.
Shared scope guard
backend/src/entities/user/utils/assert-token-scope-allowed.ts, backend/test/ava-tests/unit-tests/assert-token-scope-allowed.test.ts
Adds centralized validation for 2FA and email-verification scopes. Unknown scopes remain allowed.
Authentication integration and validation
backend/src/authorization/*, backend/src/microservices/agents-microservice/..., backend/test/ava-tests/unit-tests/*
Replaces inline 2FA checks with the shared guard and tests middleware-related token, DTO, and use-case behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to b564d

The PR adds email-verification scope enforcement and its supporting error contract; no actionable merge-blocking risk remains, and it is merge-ready after normal checks.

A rabbit checks the token trail
Two scopes hop beneath the veil
The guard sorts what may pass
Unknown scopes skip through the grass
Email and 2FA stand clear
Tests thump softly: “all is here”

Explanation

The new EMAIL_VERIFY restriction has an authentication bypass. The pull request calls assertTokenScopeAllowed() in four paths, but NonScopedAuthMiddleware remains unchanged and does not call it. UserModule applies NonScopedAuthMiddleware to /user/otp/generate, /user/otp/verify, and /user/otp/disable. A valid email_verify session can therefore reach these state-changing OTP endpoints without email verification. This contradicts the stated restriction and leaves a malicious or unverified session able to change OTP state and obtain an OTP secret.

Resolution

Update NonScopedAuthMiddleware to call assertTokenScopeAllowed(data.scope, [JwtScopesEnum.TWO_FA_ENABLE]) after JWT verification. This preserves the existing 2FA-enrolment exception while rejecting EMAIL_VERIFY tokens and other restricted scopes. Add integration tests that exercise all three /user/otp/* routes with an email_verify token.

Use an arrow function for assertTokenScopeAllowed.

Line 12 introduces a function declaration. Convert this exported utility to a const arrow function to follow the project rule.
