In
`@src/main/java/org/sopt/buddys/domain/chat/controller/ChatRoomController.java`:
- Line 153: Update ChatReportMailSender.buildHtmlBody to HTML-encode all
user-derived values—reason, nickname, and email—before inserting them into the
mail body or links, while preserving the intended rendered content for normal
input. Add a regression test covering malicious markup in the report reason.
In
`@src/main/java/org/sopt/buddys/domain/chat/controller/swagger/ReportChatPartnerSwagger.java`:
- Around line 62-75: ReportChatPartnerSwagger의 메일 발송 실패를 나타내는 500 응답 정의를 제거하고,
신고 접수 성공을 나타내는 200 응답 문서는 유지하세요. 메일 발송 실패가 신고 접수 결과에 영향을 주지 않는다는 설명이 필요하면 해당 200
응답 설명에만 반영하세요.
In
`@src/main/java/org/sopt/buddys/domain/chat/service/ChatMessageCommandService.java`:
- Line 40: 직렬화 경계를 통일해 `sendMessage`의 `validateNotBlocked` 검사와 메시지 저장이 채팅방 행에 대한
`PESSIMISTIC_WRITE` 잠금 아래 실행되도록 하고, `blockChatPartner`도 동일한 채팅방 행을 같은 방식으로 잠근 뒤
차단 레코드를 저장하도록 수정하세요. 차단 커밋과 동시에 메시지를 보내는 경쟁 상황에서 차단 이후 메시지가 저장되지 않는 통합 테스트를
추가하세요.
In `@src/main/java/org/sopt/buddys/domain/chat/service/ChatReportMailSender.java`:
- Line 41: Update buildHtmlBody and the ChatReportMailSender email formatting
flow to HTML-escape all dynamic values before inserting them into the HTML body:
reason, reporter and reported nicknames, and reporter and reported email
addresses. Preserve the existing formatting and email content while ensuring
every request-derived value is escaped before interpolation.
- Around line 50-51: Update ChatReportMailSender to catch SdkClientException
alongside SesV2Exception and convert it to BaseException with
ChatErrorCode.REPORT_MAIL_SEND_FAILED. Add a test verifying that an
SdkClientException during sendEmail is handled through
ChatUserReportService.sendReportMail and returns a successful API response
without duplicating the saved report.
In
`@src/main/java/org/sopt/buddys/domain/chat/service/ChatUserReportService.java`:
- Line 21: Update reportChatPartner so the synchronous sesV2Client.sendEmail
call executes outside any transaction, either after the transactional work
completes or through a NOT_SUPPORTED propagation boundary. Preserve
ChatUserReportCommandService.save and its REQUIRES_NEW transaction behavior.

신고나 기존 채팅 서비스에서는 deletedAt 기준으로 활성 사용자인지 먼저 확인하고 있는데 차단 쪽에는 해당 검증이 없는 것 같아요! 차단에서도 탈퇴한 사용자의 요청을 막도록 동일하게 활성 사용자 검증을 추가하면 어떨까요??

sendMessage가 방 잠금을 획득하기 전에 생성한 스냅샷을 사용하지 않도록 수정하세요.
sendMessage는 getActiveUser와 멤버십 조회를 먼저 실행한 뒤 findByIdForUpdate를 호출합니다. MySQL의 기본 repeatable-read 동작에서는 이 선행 조회가 스냅샷을 만들 수 있습니다. 이후 reportChatPartner의 REQUIRES_NEW 트랜잭션이 신고를 커밋하고 sendMessage가 방 잠금을 획득해도, 잠금이 없는 existsReportBetween은 이전 스냅샷을 읽어 신고를 누락할 수 있습니다. 그러면 ChatMessageRepository.save가 메시지를 저장합니다.
이는 커밋된 신고 상대에게 메시지를 보낼 수 없다는 계약을 위반합니다. 수정 책임은 ChatMessageCommandService.sendMessage의 트랜잭션 경계에 있습니다. 방 잠금을 모든 일반 조회보다 먼저 획득하거나, 해당 트랜잭션을 READ_COMMITTED로 설정해 신고 조회가 최신 커밋 상태를 읽도록 하세요.

동시성 테스트에서 실제 sendMessage 경로를 호출하세요.
현재 테스트는 chatRoomRepository.findByIdForUpdate를 직접 호출합니다. 따라서 ChatMessageCommandService.sendMessage에서 잠금 호출을 제거해도 테스트는 통과할 수 있습니다. sendMessage를 실행한 뒤 잠금 획득 이후까지 트랜잭션을 유지하여, 메시지 전송과 blockChatPartner의 직렬화를 검증하세요.
