CVE-2026-25724
HighSummary
Claude Code to narzędzie do programowania, które przed wersją 2.1.7 nie egzekwowało rygorystycznie reguł odmowy dostępu skonfigurowanych w pliku settings.json przy dostępie do plików przez linki symboliczne. Użytkownik mógł zablokować dostęp do pliku (np. /etc/passwd), ale Claude Code mógł odczytać ten plik przez link symboliczny, omijając reguły odmowy.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do wrażliwych plików, co może prowadzić do wycieku danych lub naruszenia bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację Claude Code do wersji 2.1.7 lub nowszej, aby zapewnić prawidłowe egzekwowanie reguł odmowy dostępu.

Original NVD description (English source)
Claude Code is an agentic coding tool. Prior to version 2.1.7, Claude Code failed to strictly enforce deny rules configured in settings.json when accessing files through symbolic links. If a user explicitly denied Claude Code access to a file (such as /etc/passwd) and Claude Code had access to a symbolic link pointing to that file, it was possible for Claude Code to read the restricted file through the symlink without triggering deny rule enforcement. This issue has been patched in version 2.1.7.
