Summary by CodeRabbit

  • 새 기능

    • 주식 가격 예측을 제출하고 예측 결과를 조회할 수 있습니다.
    • 예측 기간과 목표 변동률에 따라 획득 가능 포인트가 제공됩니다.
    • 만기 예측은 자동으로 채점되며, 정답 여부와 변동률에 따라 포인트가 반영됩니다.
    • 사용자의 포인트와 누적 플레이 횟수를 계정 정보에서 확인할 수 있습니다.
    • 예측 성공·실패 및 누적 예측 기록이 사용자 포트폴리오에 반영됩니다.
  • 문서

    • 테스트용 API의 Swagger 분류명이 보다 명확하게 변경되었습니다.

Walkthrough

예측 제출·결과 조회·수동 및 자동 채점 기능을 추가했습니다. 예측 도메인과 가격 조회 포트를 구현했습니다. 사용자 포트폴리오에 예측 통계를 기록하고 사용자 정보 응답에 포인트와 플레이 횟수를 포함했습니다.

.github/pull_request_template.md, src/main/java/com/example/demo/api/common/controller/TestApiController.java
결과 캡처 안내 문구와 Swagger 태그 이름을 수정했습니다.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to b4e58

Merging now could expose users’ prediction results, let ordinary users trigger grading, duplicate points during concurrent grading, break account retrieval for existing OAuth users, and grade some new predictions earlier than requested.

In
`@src/main/java/com/example/demo/api/prediction/controller/PredictionController.java`:
- Line 43: Update the prediction-result retrieval flow in PredictionController
and PredictionUseCase.getPredictionResult to accept the authenticated User or
userId, include that user identifier in the prediction lookup condition, and
reject access when the requesting user is not the owner. Preserve the existing
successful response for predictions owned by the authenticated user.

In
`@src/main/java/com/example/demo/api/prediction/controller/PredictionTestController.java`:
- Line 30: Restrict the test-scoring endpoints in PredictionTestController,
including manualGrade and runScheduler, so they are disabled in production or
require administrator authorization; do not leave them accessible to ordinary
authenticated users, and preserve ownership or authorization checks before
invoking scoring operations.

In
`@src/main/java/com/example/demo/api/prediction/service/PredictionUseCase.java`:
- Line 75: Update PredictionUseCase.manualGrade and gradeMaturedPredictions to
make the PENDING-to-graded transition atomic, using optimistic locking or a
conditional update that verifies the affected row count. Only the request that
successfully claims the prediction may execute gradeInternal and
recordGradingResult; concurrent attempts must not duplicate point or
grading-counter updates.
- Around line 121-131: Update calcMaturityAt in PredictionUseCase to move
weekend maturity dates to the next business day rather than the preceding
Friday: Saturday should become Monday and Sunday should become Monday, while
weekday dates retain their existing date. Preserve the 15:30 maturity time.

In `@src/main/java/com/example/demo/api/user/service/UserUseCase.java`:
- Line 32: Update the existing-user flow in CustomOAuth2UserService to verify
that a portfolio exists and create it when absent, preserving the current
createPortfolio behavior for new users and the existing
UserPortfolioHandler.NOT_FOUND behavior only when appropriate.

Authorization Bypass

Reachability: External
Exploitability: Moderate
CWE: CWE-862 — Missing Authorization

테스트 채점 API를 일반 사용자에게 노출하지 마세요.

manualGrade는 호출자의 user와 예측 소유권을 확인하지 않습니다. 인증된 사용자가 다른 사용자의 predictionId로 채점을 실행할 수 있습니다. runScheduler는 모든 만기 예측을 일괄 채점합니다. 운영 환경에서는 두 API를 비활성화하거나 관리자 권한으로 제한하세요.
