Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk:🟡 Moderate · up to The RTL/LTR rendering change is localized, but the current implementation still checks a directory and then writes index.html through replaceable paths; a directory or symlink swap could redirect output elsewhere. Merge should wait for descriptor-relative or equivalent safe writes, or explicit owner acceptance of this bounded security risk. Possibly related PRs

than fully preventing the vulnerability. Implement a stronger mitigation by
binding writes to a safely opened directory handle or atomically preventing
replacement of the checked directory before createTempFile and move; do not
present the existing path-based checks or ATOMIC_MOVE as complete protection.

- Around line 486-489: Update the directory-processing flow around
process_ignore_file, Files.isDirectory, and write_index_file to retain a
validated directory handle and perform the index.html write through
SecureDirectoryStream or the platform’s descriptor-relative API, rather than
path-based temporary-file creation and move. Preserve the existing ignore and
directory behavior, and add a regression test that replaces the directory
between validation and writing.

NOFOLLOW_LINKS 검사를 완전한 방지로 기록하지 마세요.
process_dir는 검사 후 write_index_file을 호출합니다. write_index_file은 Files.createTempFile(curr_dir.toPath(), ...)와 Files.move(..., curr_dir.toPath().resolve("index.html"), ...)를 경로 기반으로 실행합니다. 그 사이에 공격자가 curr_dir를 심볼릭 링크로 교체하면 다른 디렉토리에 파일을 쓸 수 있습니다. ATOMIC_MOVE도 부모 경로의 심볼릭 링크 교체를 막지 않습니다.
안전한 디렉토리 핸들에 쓰기를 바인딩하거나 심볼릭 링크 교체를 원자적으로 차단하는 구현을 추가하세요. 구현 전에는 조치를 “TOCTOU 공격 창을 줄이는 완화”로 기록하세요.

디렉터리 핸들을 사용해 검사와 index.html 쓰기를 연결하세요.
process_ignore_file(curr_dir)가 디렉터리 검사보다 먼저 실행됩니다. 검사 후 curr_dir가 교체되면 경로 기반 Files.createTempFile(...)와 Files.move(...)가 새 디렉터리 또는 심볼릭 링크 대상에 쓰게 됩니다. SecureDirectoryStream 또는 플랫폼의 descriptor-relative API를 사용하세요. 검사 순서 변경이나 ATOMIC_MOVE만으로는 TOCTOU를 해결할 수 없습니다. 디렉터리 교체 회귀 테스트도 추가하세요.

💡 What:
html4tree가 생성하는 정적 디렉토리 파일 트리 구조 안의
<h1>요소(디렉토리 이름)와<span>요소(파일 이름)에dir="auto"속성을 부여했습니다.🎯 Why:
시스템에 따라 아랍어/히브리어 같은 우에서 좌(RTL)로 읽는 방향성을 가진 파일/디렉토리가 존재할 수 있습니다. 기본적으로 웹페이지는 좌에서 우(LTR) 뷰를 따르기 때문에, RTL 텍스트가 삽입되면 렌더링이 깨지거나 파일/확장자 명이 뒤섞여 보이는 UX 문제가 발생합니다.
dir="auto"를 설정하면 브라우저가 콘텐츠에 기반하여 방향성을 동적으로 처리합니다.📸 Before/After:
<h1>${directoryName}</h1>/<span>${fileName}</span><h1 dir="auto">${directoryName}</h1>/<span dir="auto">${fileName}</span>♿ Accessibility:
시각 장애인이나 저시력 사용자가 스크린 리더로 접근할 때뿐만 아니라, 일반 사용자들도 서로 다른 방향성의 언어가 섞인 파일 목록을 탐색할 때 올바른 텍스트 순서대로 파일을 인지할 수 있도록 다국어 웹 접근성을 높였습니다.
