Summary
Vulnerability in github.com/OpenListTeam/OpenList/v4 (CVE-2026-69160). Confidential information can be exposed externally. Exploitable via POST /api/share/create. Mitigation: upgrade to 4.2.4 or later.
Original description
The description as published by the source.
OpenList a file list program that supports multiple storage. Prior to 4.2.4, the share creation and update checks in server/handles/sharing.go use strings.HasPrefix(requested_path, user.BasePath) without enforcing a directory separator boundary. An authenticated user with CanShare permission and a BasePath such as /base can submit a sibling path such as /base2/secret.txt, create a share for the out-of-scope file, and use the public share download or list handlers to read data outside the assigned directory. This issue is fixed in version 4.2.4.

-
1Identify exposure identify
grep -r 'github.com/OpenListTeam/OpenList/v4' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
github.com/OpenListTeam/OpenList/v4を grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'POST /api/share/create' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
POST /api/share/createへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Apply patch patch
Upgrade github.com/OpenListTeam/OpenList/v4 to 4.2.4ステージング環境で 4.2.4 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 2 で見つけた異常検知の続報チェックを含めること。
-
4Post-deployment verification verify
Replay attack against POST /api/share/create on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
