CVE-2026-26960
HighSummary
node-tar to pełnofunkcjonalny program Tar dla Node.js. W wersjach 7.5.7 i poniżej, przy użyciu domyślnych opcji, złośliwy archiwum może utworzyć twardy link w katalogu ekstrakcji, który wskazuje na plik poza katalogiem głównym ekstrakcji, co umożliwia odczyt i zapis dowolnych plików jako użytkownik wykonujący ekstrakcję.
Risk Assessment
Atakujący może uzyskać dostęp do plików poza dozwolonym katalogiem, co stwarza poważne zagrożenie dla integralności i poufności danych w systemie. Może to prowadzić do nieautoryzowanego dostępu do wrażliwych informacji.
Recommendation
Zaleca się aktualizację node-tar do wersji powyżej 7.5.7 oraz przegląd konfiguracji używanych opcji, aby zminimalizować ryzyko związane z twardymi linkami w katalogu ekstrakcji.

Original NVD description (English source)
node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user.
