Review Change Stack

📝 Walkthrough

Walkthrough

카카오 OAuth 로그인·회원가입·계정 연결과 연결 해제 처리를 추가했습니다. 회원 탈퇴와 사용자 프로필 처리를 서비스로 이동했습니다. 뉴스레터 업로드를 다중 파일과 순차 OCR 방식으로 확장했습니다. 관련 설정, 마이그레이션, 오류 처리와 운영 문서를 갱신했습니다.

Changes

카카오 인증 및 계정 연결

Layer / File(s) Summary
카카오 인증 계약과 저장 구조
src/main/java/com/gachi/be/domain/auth/config/AuthProperties.java, src/main/java/com/gachi/be/domain/auth/dto/..., src/main/java/com/gachi/be/domain/auth/entity/..., src/main/resources/db/migration/V25__social_accounts.sql, src/main/resources/db/migration/V26__kakao_unlink_outbox.sql
카카오 OAuth 설정, 요청·응답 DTO, 소셜 계정 엔티티와 저장소, 일회용 토큰 계약, outbox 스키마를 추가했습니다.
카카오 OAuth 실행 흐름
src/main/java/com/gachi/be/domain/auth/api/controller/KakaoAuthController.java, src/main/java/com/gachi/be/domain/auth/service/..., src/main/java/com/gachi/be/domain/auth/service/impl/..., src/test/java/com/gachi/be/domain/auth/service/impl/*
인가, 콜백, ticket 소비, 로그인·회원가입·계정 연결, Kakao API 호출과 GACHI 토큰 발급을 구현했습니다.
카카오 연결 해제 처리
src/main/java/com/gachi/be/domain/auth/entity/KakaoUnlinkOutbox.java, src/main/java/com/gachi/be/domain/auth/service/impl/KakaoUnlinkOutbox*.java, src/main/java/com/gachi/be/domain/auth/service/impl/SocialAccountDisconnectService.java, src/test/java/com/gachi/be/domain/auth/service/impl/KakaoUnlinkOutboxProcessorTest.java
연결 해제 요청을 outbox에 기록하고, 스케줄러가 외부 API 호출과 지수 백오프 재시도를 수행하도록 했습니다.

뉴스레터 다중 파일 업로드

Layer / File(s) Summary
뉴스레터 다중 파일 업로드
src/main/java/com/gachi/be/domain/newsletter/api/controller/NewsletterController.java, src/main/java/com/gachi/be/domain/newsletter/service/..., src/main/java/com/gachi/be/domain/newsletter/entity/Newsletter.java, src/main/java/com/gachi/be/domain/newsletter/pipeline/NewsletterPipelineService.java, src/main/resources/db/migration/V27__newsletter_add_file_keys.sql
업로드 API가 파일 목록을 받고, 최대 10개 이미지 또는 단일 PDF를 검증합니다. 파일 키를 페이지 순서로 저장하고, 각 페이지를 순차적으로 다운로드·전처리·OCR합니다.

회원 탈퇴 및 운영 지원

Layer / File(s) Summary
회원 탈퇴와 프로필 처리
src/main/java/com/gachi/be/domain/user/api/controller/UserController.java, src/main/java/com/gachi/be/domain/user/service/UserProfileService.java, src/main/java/com/gachi/be/domain/user/entity/User.java, src/test/java/com/gachi/be/domain/user/api/controller/UserControllerIntegrationTest.java
언어·알림 변경 처리를 UserProfileService로 이동했습니다. 현재 비밀번호 검증, 사용자 탈퇴, refresh token 폐기, 푸시 토큰 비활성화를 추가했습니다.
실행 환경과 오류 처리
src/main/resources/application.yml, deploy/nginx/*, src/main/java/com/gachi/be/global/exception/GlobalExceptionHandler.java, docs/kakao-login.md
multipart 크기와 Nginx timeout을 조정했습니다. 요청 오류 응답과 Kakao 운영 설정 문서를 추가했습니다.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 3cf56

The release can block social-only account deletion, fail valid PDF processing, permit login during unlink, and expose login tickets to interception. Resolve these issues before deployment.

Inline comments:
In `@deploy/nginx/nginx.conf`:
- Around line 104-106: Add client_body_timeout 300s to both http blocks:
deploy/nginx/nginx.conf lines 104-106 and deploy/nginx/nginx.https.template.conf
lines 84-86. Keep the existing proxy timeout settings unchanged so client upload
timeouts match the 300-second upstream timeouts.

In
`@src/main/java/com/gachi/be/domain/auth/service/impl/KakaoAuthServiceImpl.java`:
- Line 94: Update the Kakao login flow in KakaoAuthServiceImpl to check
account.isDisconnectPending() before authTokenIssuer.issue, and reject
authentication for DISCONNECT_PENDING SocialAccount instances without issuing
access or refresh tokens.

In
`@src/main/java/com/gachi/be/domain/newsletter/pipeline/NewsletterPipelineService.java`:
- Line 86: Update NewsletterPipelineService to determine PDF handling from the
validated content type returned by validateNewsletter rather than fileKey’s
extension, preserving correct routing when the original filename lacks a .pdf
suffix or is absent; alternatively, consistently preserve the validated original
extension in S3FileServiceImpl.buildObjectKey and use that contract. Add a
regression test covering a valid PDF upload without a .pdf filename extension.

In `@src/main/java/com/gachi/be/domain/user/service/UserProfileService.java`:
- Line 134: Update UserProfileService.withdraw to support Kakao-only users whose
passwordHash is null by adding the appropriate Kakao reauthentication or
explicitly invoking the existing unlink withdrawal flow, while preserving
current-password validation for local accounts. Ensure successful Kakao
withdrawal deletes the account and revokes its tokens, and add an integration
test covering that endpoint behavior.

In `@src/main/resources/application.yml`:
- Line 63: Update the app-redirect-uri default in application.yml from the
unverified custom gachi:// scheme to the verified HTTPS Android App Link or iOS
Universal Link, and configure KAKAO_APP_REDIRECT_URI in production to use the
same verified HTTPS domain.

In
`@src/test/java/com/gachi/be/domain/auth/service/impl/RedisKakaoLoginStoreTest.java`:
- Around line 48-50: Update the valueOperations.getAndDelete stub in
RedisKakaoLoginStoreTest to match the complete key
auth:kakao:ticket:one-time-token, ensuring consume("ticket", "one-time-token")
is tested with the exact token-specific Redis key.

🌐 Web query:

site:nginx.org/en/docs/http/ngx_http_core_module.html client_body_timeout default 60s proxy_request_buffering

💡 Result:

The default value for the client_body_timeout directive is 60 seconds [1]. This directive defines the timeout period for reading the client request body, applying specifically to the interval between two successive read operations rather than the transmission of the entire body [1]. If a client fails to transmit data within this period, the request is terminated with a 408 (Request Time-out) error [1]. Regarding proxy_request_buffering, the provided documentation does not specify its default value [1]. This directive is typically associated with the ngx_http_proxy_module, not the ngx_http_core_module [1].

두 Nginx 설정에 client_body_timeout 300s;를 추가하세요.

/api/proxy_request_buffering on은 요청 본문을 upstream으로 전달하기 전에 읽습니다. proxy_send_timeoutproxy_read_timeout은 클라이언트 업로드에 적용되지 않습니다. client_body_timeout이 없으므로 기본값 60초가 적용되며, 60초 동안 데이터가 수신되지 않으면 요청이 종료됩니다.

http 블록에 다음 설정을 추가해 업로드 타임아웃을 300초로 일치시키세요.

검증된 미디어 타입을 함께 저장하여 PDF 여부를 판별하거나, 업로드 시 키에 원본 확장자를 보존하는 계약을 적용하고 PDF 업로드 회귀 테스트를 추가하세요.

카카오 가입은 passwordHashnull로 저장합니다. 따라서 BCryptPasswordEncoder.matches(..., null)false를 반환하고, UserProfileService.withdrawAUTH_INVALID_CREDENTIALS로 요청을 거부합니다. 런타임 예외는 발생하지 않습니다. changePassword도 같은 검증을 사용하므로 로컬 비밀번호를 추가할 수 없습니다. 기존 Kakao unlink는 비동기 웹훅 이후에만 소셜 전용 계정을 탈퇴 처리하므로 이 엔드포인트의 성공 경로를 대체하지 않습니다.

In `@src/main/java/com/gachi/be/domain/user/service/UserProfileService.java` at
line 134, Update UserProfileService.withdraw to support Kakao-only users whose
passwordHash is null by adding the appropriate Kakao reauthentication or
explicitly invoking the existing unlink withdrawal flow, while preserving
current-password validation for local accounts. Ensure successful Kakao
withdrawal deletes the account and revokes its tokens, and add an integration
test covering that endpoint behavior.

Broken Authentication (CWE-939)

Reachability: External · Exploitability: Moderate

검증된 HTTPS 앱 링크로 리디렉션 URI를 교체하십시오.

app-redirect-uri의 기본값은 소유권 검증이 없는 gachi:// 사용자 지정 스킴입니다. OAuth 콜백은 bearer ticket을 이 URI로 전달합니다. 악성 앱이 같은 스킴을 등록하면 ticket을 가로채 공개된 /complete 엔드포인트에 전달할 수 있습니다. 기존 계정이면 피해자 계정의 로그인 토큰이 발급됩니다. Android App Link 또는 iOS Universal Link를 사용하고, 운영 환경의 KAKAO_APP_REDIRECT_URI도 동일한 검증된 HTTPS 도메인을 사용하도록 구성하십시오.

티켓 키 전체를 검증하도록 matcher를 구체화하세요.

RedisKakaoLoginStore.consume("ticket", "one-time-token")key(purpose, token)을 통해 auth:kakao:ticket:one-time-token을 조회합니다. 현재 startsWith("auth:kakao:ticket:")는 토큰 값을 검증하지 않으므로, 잘못된 토큰을 조회해도 테스트가 통과할 수 있습니다. 정확한 키를 사용하세요.

-import static org.mockito.ArgumentMatchers.startsWith;
-
-    when(valueOperations.getAndDelete(startsWith("auth:kakao:ticket:")))
+    when(valueOperations.getAndDelete("auth:kakao:ticket:one-time-token"))
         .thenReturn(json)
         .thenReturn(null);
