Problem

The production CORS middleware permitted only GET, POST, and OPTIONS, while the registered API and frontend also use PUT and DELETE. Browsers therefore rejected valid cross-origin mutations during preflight. The repository currently exposes no PATCH route, so PATCH must remain denied rather than being pre-authorized speculatively.

Implemented fix

  • added a production-app preflight regression for the verified API surface: GET, POST, PUT, DELETE, and OPTIONS;
  • added a negative regression proving unexposed PATCH requests receive a 400 preflight response and are absent from Access-Control-Allow-Methods;
  • committed the negative regression first (dd096deb87e6f07d8a2a15ca7f935c3012f3d166), before tightening production configuration;
  • retained an explicit method allowlist rather than *;
  • added PUT and DELETE to the production CORSMiddleware configuration while keeping PATCH denied;
  • preserved existing origins, headers, credential policy, middleware order, and API behavior;
  • kept the change bounded to the production configuration and its regression test.

This clean replacement supersedes closed #694, whose final branch no longer contained the advertised CORS change and had accumulated unrelated rate-limiter work.

Exact-head validation

Current head: 6ecb76fe10b76cc1c1359d5fa2a7ee497cdd5980.

Exact-head CI, security gates, automated review, unresolved threads, and independent non-author approval must be revalidated after the current-head fix. The PR must not merge until repository policy and every required gate pass on this exact head.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 32 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

@seonghobae Reviewed exact head c319bed12b081f99e03324cf95925b1e139b2f14. I found no review findings.

  • The PR changes exactly two files: backend/app/main.py and backend/tests/test_cors_methods.py.
  • CORSMiddleware has the explicit allowlist: GET, POST, PUT, PATCH, DELETE, and OPTIONS.
  • The new regression test issues an OPTIONS preflight for every allowlisted method. It verifies a successful response and the method in Access-Control-Allow-Methods.
  • The PR preserves configured origins, CORS_ALLOW_HEADERS, allow_credentials=False, and middleware registration order.
  • Exact-head checks succeeded for backend, frontend, Semgrep, OSV, Trivy, CodeQL, and CodeRabbit. The exact-head commit status is also successful.
  • GitHub reports zero unresolved review threads.

GitHub still reports REVIEW_REQUIRED and BLOCKED. The PR must not merge until the required repository approval is present and required checks remain successful on this head.

@seonghobae I found one blocking issue. I cannot approve this exact head.

backend/app/main.py, Line 135, allows PATCH. The production source has no PATCH route registration. The frontend source also has no PATCH request. The only HTTP PATCH references are the new CORS allowlist and backend/tests/test_cors_methods.py.

This makes the allowlist broader than the verified production API surface. It does not meet the requested fail-closed boundary.

Remove PATCH from the allowlist and regression test, or add evidence of the production PATCH endpoint and its client use. The remaining requested checks are satisfactory:

  • The scope is limited to two files.
  • Origins, allowed headers, credentials, and middleware order are unchanged.
  • The regression performs real CORS preflight requests.
  • Exact-head backend, frontend, security, SAST, and CodeRabbit checks succeeded.
  • GitHub reports zero unresolved review threads.

@seonghobae Formal current-head verdict: REQUEST CHANGES. I cannot approve c319bed12b081f99e03324cf95925b1e139b2f14.

backend/app/main.py, Line 135, allows PATCH. The production route declarations contain GET, POST, PUT, and DELETE, but no PATCH route. The source search found no production PATCH request. The other PATCH matches are unrelated Python unittest.mock.patch calls and test metrics data.

The regression verifies preflight handling for each configured method. It does not verify that each method is part of the production API surface. Therefore, PATCH makes the CORS boundary broader than the verified API boundary.

Remove PATCH from allow_methods and API_CORS_METHODS, or add the supported production PATCH endpoint and its API contract.

All other requested conditions are satisfactory:

  • The exact head matches the requested SHA.
  • The PR changes only backend/app/main.py and backend/tests/test_cors_methods.py.
  • The allowlist remains explicit.
  • The regression sends real CORS preflight requests.
  • Origins, allowed headers, allow_credentials=False, and middleware registration order are unchanged.
  • Exact-head backend, frontend, security, SAST, CodeQL, and CodeRabbit checks succeeded.
  • GitHub reports zero unresolved review threads.

Exact-head independent review requested for c319bed12b081f99e03324cf95925b1e139b2f14. Complete CI, backend/frontend verification, Security Scan, Semgrep, and CodeRabbit status are clean with no unresolved threads. @opencode-agent @cwl-noema-review please verify the explicit GET/POST/PUT/PATCH/DELETE/OPTIONS preflight allowlist, unchanged origin/header/credential policy, production-app regression coverage, and two-file scope. Submit APPROVE only for this SHA.

Review exact current head 6ecb76fe10b76cc1c1359d5fa2a7ee497cdd5980 against protected main. Complete CI, Security Scan, SAST Semgrep, and CodeRabbit status are successful on this SHA, with no unresolved review thread. Verify the explicit production CORS method allowlist matches the registered API surface, accepts GET/POST/PUT/DELETE/OPTIONS, rejects unexposed PATCH, preserves all other middleware policy, and remains limited to the two intended files. Submit APPROVE only if no blocking finding remains.

@seonghobae Approved exact head 6ecb76fe10b76cc1c1359d5fa2a7ee497cdd5980.

I found no blocking issue.

  • The PR changes only backend/app/main.py and backend/tests/test_cors_methods.py.
  • The production allowlist is explicit: GET, POST, PUT, DELETE, and OPTIONS.
  • The registered API routes use GET, POST, PUT, and DELETE. The route search found no production PATCH route.
  • The regression sends real CORS preflight requests for every allowed method.
  • The regression verifies that an unexposed PATCH preflight returns 400 and is absent from Access-Control-Allow-Methods.
  • The diff preserves origin policy, allowed-header policy, allow_credentials=False, and middleware registration order.
  • Exact-head backend, frontend, security, SAST, CodeQL, and CodeRabbit checks are successful.
  • GitHub reports zero unresolved review threads.

Please review exact head 6ecb76fe10b76cc1c1359d5fa2a7ee497cdd5980. Exact-head CI, Security Scan, and Semgrep are successful, and no inline review threads exist. Verify the positive preflight contract for GET, POST, PUT, DELETE, and OPTIONS, the explicit negative PATCH contract, preservation of the existing origin/header/credential policy, and the two-file bounded diff. Publish findings or an exact-head verdict only; do not reuse predecessor PR #694 evidence.
