GareArc eba0041973 fix(openapi): close 4 critical OAuth device-flow security findings
1. Host-header injection (sso_initiate / sso_complete): replace
   request.host_url with dify_config.CONSOLE_API_URL via a
   _trusted_origin() helper that fails closed when unset. An
   attacker-controlled Host header on sso-initiate would otherwise
   be sealed into the signed state envelope, causing the IdP to
   redirect the victim's EE-signed SSO assertion to evil.com.

2. Unvalidated JWS claim payloads: add ExtSubjectAssertionClaims
   and ApprovalGrantClaimsPayload pydantic models and route every
   verified payload through model_validate. A signed-but-malformed
   blob now returns BadRequest('invalid_sso_assertion') or
   VerifyError('claim shape invalid') instead of crashing the
   handler with KeyError / 500. ApprovalGrantClaimsPayload is
   imported lazily inside verify_approval_grant to break the
   libs -> controllers cycle.

3. Timing-unsafe CSRF compare in approve_external: replace plain
   != with secrets.compare_digest.

4. Bearer rate-limit bypass on revoked tokens: move
   enforce_bearer_rate_limit to fire after sha256_hex but before
   resolver.resolve, so revoked-token replay is now bounded. Also
   collapse the two distinct error messages (unknown token prefix
   vs token unknown or revoked) into a single generic
   'invalid_bearer' to remove the prefix-validity oracle.

Tests: 4 new unit-test files cover each finding plus one updated
test for the new bearer error string. 744 tests pass.

Dify Backend API

Setup and Run

Important

In the v1.3.0 release, poetry has been replaced with uv as the package manager for Dify API backend service.

uv and pnpm are required to run the setup and development commands below.

The scripts resolve paths relative to their location, so you can run them from anywhere.

  1. Run setup (copies env files and installs dependencies).

    ./dev/setup
    
  2. Review api/.env, web/.env.local, and docker/middleware.env values (see the SECRET_KEY note below).

  3. Start middleware (PostgreSQL/Redis/Weaviate).

    ./dev/start-docker-compose
    
  4. Start backend (runs migrations first).

    ./dev/start-api
    
  5. Start Dify web service.

    ./dev/start-web
    

    ./dev/setup and ./dev/start-web install JavaScript dependencies through the repository root workspace, so you do not need a separate cd web && pnpm install step.

  6. Set up your application by visiting http://localhost:3000.

  7. Start the worker service (async and scheduler tasks, runs from api).

    ./dev/start-worker
    
  8. Optional: start Celery Beat (scheduled tasks).

    ./dev/start-beat
    

Environment notes

Important

When the frontend and backend run on different subdomains, set COOKIE_DOMAIN to the sites top-level domain (e.g., example.com). The frontend and backend must be under the same top-level domain in order to share authentication cookies.

  • Generate a SECRET_KEY in the .env file.

    bash for Linux

    sed -i "/^SECRET_KEY=/c\\SECRET_KEY=$(openssl rand -base64 42)" .env
    

    bash for Mac

    secret_key=$(openssl rand -base64 42)
    sed -i '' "/^SECRET_KEY=/c\\
    SECRET_KEY=${secret_key}" .env
    

Testing

  1. Install dependencies for both the backend and the test environment

    cd api
    uv sync --group dev
    
  2. Run the tests locally with mocked system environment variables in tool.pytest_env section in pyproject.toml, more can check Claude.md

    cd api
    uv run pytest                           # Run all tests
    uv run pytest tests/unit_tests/         # Unit tests only
    uv run pytest tests/integration_tests/  # Integration tests
    
    # Code quality
    ./dev/reformat               # Run all formatters and linters
    uv run ruff check --fix ./   # Fix linting issues
    uv run ruff format ./        # Format code
    uv run pyrefly check         # Type checking
