CVE-2026-25722
CriticalSummary
Claude Code to narzędzie do kodowania, które przed wersją 2.0.57 nieprawidłowo weryfikowało zmiany katalogów w połączeniu z operacjami zapisu w chronionych folderach. Umożliwiało to obejście ochrony zapisu i tworzenie lub modyfikowanie plików bez potwierdzenia użytkownika.
Risk Assessment
Organizacje mogą być narażone na nieautoryzowane zmiany w wrażliwych plikach, co może prowadzić do utraty danych lub naruszenia bezpieczeństwa. Wykorzystanie tej podatności wymagało jednak możliwości dodawania nieufnych treści do okna kontekstowego Claude Code.
Recommendation
Zaleca się aktualizację do wersji 2.0.57, aby usunąć tę podatność. Dodatkowo warto wprowadzić dodatkowe kontrole dostępu do wrażliwych katalogów.

Original NVD description (English source)
Claude Code is an agentic coding tool. Prior to version 2.0.57, Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window. This issue has been patched in version 2.0.57.
