## Summary

**DB 없이 URL**로만 정보 저장 방식을 사용하여 **안전성**과 **간편성**을 제공합니다.  
이 서비스를 통해 **마크다운 문서**를 누구나 쉽게 작성하고 **URL 공유**만으로 전달할 수 있습니다.  
외부 플랫폼에 정보를 넘길 필요 없이 독립적인 **문서 관리**가 가능합니다.  
노션과 옵시디언의 불편함을 해소하는 **대안 솔루션**으로 개발되었습니다.

## Topic Body

### 왜 MDshare인가?  
- DB따위 쓰지 않고 URL로 모든 정보를 저장하는 **호방함**과 안전함, 그리고 간단함  
- 마크다운은 마인크래프트 다운로드라고 생각하는 일반인들과도 마크다운 문서를 쉽게 공유 가능  
- 노션같은 대기업에게 정보를 넘길 필요 전혀 X  
- 장황한 URL로 시선 끌 수 있음  
### 서비스 소개  
- .md파일 업로드 혹은 textarea에서 직접 마크다운 문서 작성 가능  
- URL 그대로 다른 사람들에게 공유 가능  
- 옵시디언은 notion page같은 기능이 없고 노션은 자꾸 컴퓨터 켤때마다 열리는게 짜증나서 notion page의 대안으로서 제작

LaTeX 렌더링만 가능하면 정말 실용적으로 사용할 수 있을 것 같습니다. 아이디어도 재밌고 잘 봤습니다!

HTTP 표준(RFC 2616) 자체에는 URI 길이에 대한 명시적인 제한이 없습니다. 서버는 자신이 제공하는 모든 리소스의 URI를 처리할 수 있어야 하며, GET 기반 폼을 통해 무한한 길이의 URI가 생성될 수 있는 경우 이를 처리할 수 있어야 합니다.  
  
와 이건 몰랐네요 ㅋㅋ

마크다운내 HTML을 삽입할 경우 JavaScript가 실행 가능한 XSS 취약점이 있습니다.  
URL을 열어 볼 때 바로 삽입된 JavaScript가 실행 가능한데, 이 부분은 JavaScript가 실행되지 않도록 조치해주시는게 좋을 것 같아요.

`[javscript link](javascript:alert(document.domain))` 과 같이 클릭 링크 (href) 속성을 javascript으로 지정하는 텍스트를 공유한다면, stored XSS와 같은 공격으로 악용될 수 있습니다. PoC: https://mdshare060114.web.app/?edit=false#W2pzIGxpbmtdKGphdmFzY3JpcHQ6YWxlcnQoZG9jdW1lbnQuZG9tYWluKSk%3D
