Summary
OpenClaude to interfejs wiersza poleceń dla agentów kodowania, który ma lukę logiczną w funkcji `bashToolHasPermission()`. W wersjach przed 0.5.1, przy aktywnej funkcji automatycznego zezwalania w piaskownicy, funkcja ta zwraca wynik `allow` przed oceną filtrów ograniczeń ścieżek, co pozwala na obejście ograniczeń katalogów.
Risk Assessment
Luka ta umożliwia atakującym wykonywanie poleceń zawierających sekwencje przejścia do katalogu, co może prowadzić do nieautoryzowanego dostępu do wrażliwych plików systemowych. Organizacje mogą być narażone na poważne naruszenia bezpieczeństwa danych.
Recommendation
Zaleca się aktualizację OpenClaude do wersji 0.5.1 lub nowszej, aby załatać tę lukę. Dodatkowo, warto skonfigurować odpowiednie reguły odmowy, aby zwiększyć bezpieczeństwo systemu.

Original NVD description (English source)
OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Versions prior to 0.5.1 have a logic flaw in `bashToolHasPermission()` inside `src/tools/BashTool/bashPermissions.ts`. When the sandbox auto-allow feature is active and no explicit deny rule is configured, the function returns an `allow` result immediately — before the path constraint filter (`checkPathConstraints`) is ever evaluated. This allows commands containing path traversal sequences (e.g., `../../../../../etc/passwd`) to bypass directory restrictions entirely. Version 0.5.1 contains a patch for the issue.
