🛡️ Sentinel: 검색 엔진 연동 정보 노출 방지 by seonghobae · Pull Request #304 · ContextualWisdomLab/html4tree

seonghobae · 2026-07-29T21:04:27Z

🚨 Severity: MEDIUM
💡 Vulnerability: 정적 HTML 디렉토리 인덱서가 공개 웹 서버에 호스팅될 때, 검색 엔진 크롤러에 의해 전체 디렉토리 구조와 파일명이 색인되어 민감한 정보가 노출될 수 있는 취약점.
🎯 Impact: 검색 엔진에 의해 내부 디렉토리 구조 및 파일명이 노출되어 악의적인 공격자에게 시스템 정보를 제공할 수 있음.
🔧 Fix: HTML <head> 영역에 <meta name="robots" content="noindex, nofollow"> 태그를 추가하여 검색 엔진의 색인(indexing) 및 링크 추적(following)을 방지함.
✅ Verification: 생성된 HTML 소스 코드에 해당 메타 태그가 포함되어 있는지 확인 완료.

+## 2026-07-29 - [html4tree] 검색 엔진 인덱싱을 통한 정보 노출 (Information Exposure)
+**Vulnerability:** 정적 HTML 디렉토리 인덱서가 공개 웹 서버에 호스팅될 때, 검색 엔진 크롤러에 의해 전체 디렉토리 구조와 파일명이 색인되어 민감한 정보가 노출될 수 있는 취약점입니다.
+**Learning:** 디렉토리 내용을 나열하는 정적 HTML을 생성할 때, 명시적으로 검색 엔진 크롤링을 방지하지 않으면 의도치 않게 내부 구조와 파일명이 구글 등의 검색 결과에 노출될 수 있습니다.
+**Prevention:** 생성되는 HTML의 <head> 영역에 항상 <meta name="robots" content="noindex, nofollow"> 태그를 포함하여 검색 엔진이 해당 페이지를 색인하거나 링크를 따라가지 않도록 강제해야 합니다.


🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
robots 메타 태그의 보장 범위를 정확히 기록하세요.
noindex, nofollow는 해당 지시를 준수하는 검색 엔진 크롤러에 대한 안내입니다. 이 태그는 동작을 강제하지 않으며, 직접 접근 가능한 파일이나 비준수 크롤러를 보호하지 않습니다. 서버 측 인증 또는 접근 제어도 대체하지 않습니다.
예방책에 “준수하는 크롤러의 색인과 링크 추적을 줄인다”고 명시하고, 민감한 콘텐츠에는 별도의 서버 측 접근 제어가 필요하다고 기록하세요.

Closing as superseded by draft canonical #349. The same noindex, nofollow directive is retained there under the accurate boundary that cooperative indexing hints are not authentication or confidentiality controls and require a crawler to fetch the page. #349 is blocked pending post-#363 update, Google Search Central APA 7 doctoring, changelog, product-level tests, fresh exact-head checks, and independent approval. No evidence from this duplicate head is reused.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
