Summary of ChangesHello @toapuro, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! このプルリクエストは、MkDocsのビルドプロセスに新しいフックを導入し、全てのマークダウン形式のドキュメントを単一のテキストファイルに自動的に結合する機能を追加します。これは主にAIによるドキュメントの利用を容易にすることを目的としており、ドキュメント全体を一括で処理できるようになります。 Highlights

Code Review
This pull request introduces an mkdocs build hook to aggregate all markdown files into a single file for AI consumption. However, the implementation in hooks/gather.py lacks security checks for symbolic links, which poses a risk of arbitrary file read or file overwrite attacks in the build environment (e.g., CI/CD pipelines). Additionally, the generated docs/all.txt file should not be version controlled and should be added to .gitignore. A small fix is also recommended for the merging script to ensure consistent output across different operating systems.

hooks/gather.py (7-12)
The gather_md function is vulnerable to an arbitrary file read and potential file overwrite attack because it follows symbolic links without validation. An attacker could exploit this by committing a symbolic link to read sensitive files (e.g., /etc/passwd) or overwrite critical files in the build environment, potentially leading to Remote Code Execution (RCE) in the CI/CD pipeline. To remediate this, ensure that symbolic links are skipped or validated. Additionally, for consistent output across different operating systems, the path separator generated by md.relative_to(src_dir) should be normalized to / using as_posix().
md_files = [f for f in src_dir.rglob("*.md") if not f.is_symlink()]
md_files.sort()
if out_file.exists() and out_file.is_symlink():
return
with out_file.open("w", encoding="utf-8") as out:
for md in md_files:
out.write(f"\n\n# [{md.relative_to(src_dir)}]\n\n")
out.write(md.read_text(encoding="utf-8"))
References
- Avoid following symbolic links without validation, especially when processing user-controlled input or files in a build environment, as this can lead to arbitrary file read or write vulnerabilities.
docs/all.txt (1)
生成されたファイル docs/all.txt は、バージョン管理に含めるべきではありません。
ソースとなるマークダウンファイルが変更されるたびにこのファイルも変更されるため、リポジトリの履歴が肥大化する原因となります。
このファイルはビルドプロセス中に生成される一時的なファイルとして扱い、.gitignore に追加することをお勧めします。
