로그인·권한·입력 처리의 보안 문제 검토하기

security-review · 스킬 지원 에이전트

공식 배포스킬 설치AI 요금 확인

입력 검증, 인증·권한과 민감정보 처리를 보며 근거가 있는 보안 문제를 정리합니다.

어떤 스킬인가요?

로그인 기능이나 파일 업로드를 바꾼 뒤 놓친 위험이 없는지 검토할 때 활용합니다. 문자열 하나를 보고 위험하다고 단정하기보다 사용자 입력이 실제로 어디까지 전달되는지 추적합니다.

대상 코드와 접근 권한, 이미 적용한 보호 장치를 함께 알려주세요. 발생 조건과 영향, 확인 수준을 구분한 결과를 받을 수 있습니다. 자동 점검이 서비스 전체의 안전을 보증하지는 않으므로 중요한 변경은 테스트와 별도 검토를 함께 진행합니다.

이렇게 요청해보세요

security-review로 이 로그인과 파일 업로드 코드를 검토해줘. 권한 우회·입력 처리·민감정보 노출을 중심으로 경로와 근거를 적고 수정 방향을 제안해줘.

받을 수 있는 결과취약점 후보와 근거·수정 방향

주소의 문자열이 화면으로 들어오는 경로 검토

2026-10-05 두 줄의 격리 예제를 수동 검토했습니다. 브라우저 공격 실행이나 운영 사이트 보안 진단은 수행하지 않았습니다.

어디서 들어와 어디에 쓰이는가

이 예제는 URL의 name 값을 읽어 화면에 넣습니다. 검토할 부분은 값의 출처와 삽입 방식입니다. 전체 두 줄을 확인했을 때 별도의 정제 과정이 없었고, 입력을 HTML로 해석하는 innerHTML에 전달하고 있었습니다.

const value = new URLSearchParams(location.search).get("name");
document.querySelector("#name").innerHTML = value;

이름을 표시하려는 목적에 맞는 수정

이름을 글자로 보여주려는 경우에는 HTML 해석이 필요하지 않습니다. textContent로 바꾸면 값을 텍스트로 넣습니다. HTML 편집기를 만드는 경우에는 요구사항이 다르므로 같은 수정안을 그대로 적용할 수 없습니다.

document.querySelector("#name").textContent = value || "";

결과를 어디까지 믿을 수 있나

확인한 것은 이 작은 코드의 입력 흐름과 위험한 삽입 방식입니다. 실제 앱의 로그인, 저장소, 서버 API까지 검토한 것은 아닙니다. 스킬에 변경 파일뿐 아니라 입력을 만드는 코드와 주변 설정도 주고, 발견 사항마다 재현 조건을 설명해달라고 요청하세요.

처음 사용한다면

  1. 설치하고 준비하기

    스킬 지원 에이전트와 코드 접근이 필요합니다. 운영 환경 공격 실행은 별도 승인 범위이며 이 소개의 사용 예시는 코드 검토입니다.

    설치 요청
    https://github.com/getsentry/skills 에서 skills/security-review 스킬을 현재 에이전트의 스킬 폴더에 설치해줘. SKILL.md와 이 스킬이 참조하는 scripts·references·assets와 공통 파일을 함께 유지하고, 필요한 실행 환경과 추가 연결을 확인한 뒤 알려줘. 설치가 끝나면 security-review 스킬을 인식하는지 확인해줘.

  2. 스킬 이름과 자료를 함께 요청하기

    “security-review 스킬을 사용해줘. 입력 자료: 코드·인증 흐름·입력 경로”처럼 요청하세요. 위의 예시를 내 자료에 맞게 바꿔도 좋아요.

  3. 결과 확인하기

    예상 결과는 ‘취약점 후보와 근거·수정 방향’입니다. 필요한 내용이 포함됐는지 확인하세요. 입력 자료의 사실·숫자와 결과를 대조하고, 부족한 부분을 이어서 요청하세요.

      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
