CVE-2026-27496
HighSummary
n8n to platforma automatyzacji procesów roboczych typu open source. Przed wersjami 1.123.22, 2.9.3 i 2.10.1, uwierzytelniony użytkownik z uprawnieniami do tworzenia lub modyfikowania procesów roboczych mógł wykorzystać JavaScript Task Runner do alokacji niezainicjowanych buforów pamięci.
Risk Assessment
Niezainicjowane bufory mogą zawierać pozostałe dane, co stwarza ryzyko ujawnienia wrażliwych informacji. Organizacje mogą być narażone na wycieki danych, co może prowadzić do naruszenia prywatności i bezpieczeństwa.
Recommendation
Zaleca się aktualizację n8n do najnowszych wersji, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt uprawnień użytkowników, aby ograniczyć dostęp do funkcji tworzenia i modyfikowania procesów roboczych.
