🛡️ Sentinel: [HIGH] ERD 도구 SQL 인젝션 취약점 패치 및 기능 확장 by seonghobae · Pull Request #328 · ContextualWisdomLab/argos

seonghobae · 2026-07-26T21:45:28Z

이 PR은 ERD(ERDModel) 코어 엔진의 SQL 인젝션 취약점(DDL 생성 중 타입 선언에서 발생)을 수정하고 누락되었던 핵심 기능들을 자체적으로 판단하여 추가했습니다.

수정 사항 및 구현 내용 (한국어 기준)

보안 (Security): assertSafeSqlType 함수를 도입하여 컬럼 타입 문자열 내부에 세미콜론(;) 같은 SQL 구문 종료 문자가 삽입되는 것을 엄격히 차단했습니다. 이를 통해 DDL 스크립트 기반 SQL 인젝션 공격 표면을 제거했습니다.
기능 강화 (Features):
- removeTable(name): 테이블을 완전히 삭제하며, 해당 테이블을 참조하고 있는 모든 외래키(Foreign Key) 제약 조건들을 다른 테이블들에서 연쇄 삭제(Cascade) 처리합니다.
- removeColumn(tableName, columnName): 특정 컬럼을 삭제하며 해당 컬럼이 관련된 외래키(자체에서 참조하거나, 다른 곳에서 이 컬럼을 참조하는 경우 모두)를 안전하게 연쇄 삭제합니다.
- isUnique 속성 추가: 컬럼 생성 시 UNIQUE 제약 조건을 추가할 수 있도록 DDL 생성 로직을 개선했습니다.
테스트 (Testing): 새로 추가된 removeTable, removeColumn, UNIQUE 기능, 그리고 SQL 인젝션 필터링 예외 처리에 대한 유닛 테스트들을 완벽히 작성하여 **테스트 커버리지 100%**를 달성했습니다.
문서화 (Documentation): .jules/sentinel.md 파일에 취약점 발견 및 조치 내역을 한글로 새롭게 기록하였으며, CHANGELOG.md에도 보안 패치와 신규 기능을 한글로 정확히 정리했습니다.

Warning

Review limit reached

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

Next review available in: 7 seconds

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.

세미콜론 블랙리스트만으로는 DDL 주입을 막지 못합니다.

integer NOT NULL, injected BOOLEAN처럼 세미콜론 없이 컬럼 정의를 추가하는 타입은 통과합니다. 또한 검증은 addColumn()에서 한 번만 실행되므로, 호출자가 보유한 column 객체나 getTable() 결과를 수정하면 이후 generateDDL()에서 검증 없이 삽입됩니다. DDL 생성 직전에 허용 목록/파서 기반으로 타입을 검증하고, 세미콜론 없는 주입 및 검증 후 변조 회귀 테스트를 추가하세요.

assertSafeSqlType is enforced on addColumn, but generateDDL still interpolates col.type directly. Since callers can obtain mutable table/column objects via getTable() / getTables() and mutate type after validation, it’s safer to defensively validate again at DDL generation time.

 **Learning:** Never use custom 'homebrew' buffer-padding logic to match lengths for `crypto.timingSafeEqual()`, as early returns leak the length of the secret.
 **Prevention:** Ensure inputs are hashed to a uniform length (e.g., using `crypto.createHash('sha256')`) before comparison.
