CVE-2025-49619
HighSummary
Skyvern w wersji do 0.1.85 jest podatny na wstrzykiwanie szablonów po stronie serwera (SSTI) w polu Prompt bloków roboczych, takich jak blok Nawigacji v2. Niewłaściwe oczyszczanie danych wejściowych szablonu Jinja2 pozwala uwierzytelnionym użytkownikom na wstrzykiwanie stworzonych wyrażeń, które są oceniane na serwerze, co prowadzi do zdalnego wykonania kodu (RCE).
Risk Assessment
Podatność ta może umożliwić atakującym uzyskanie pełnej kontroli nad serwerem, co stwarza poważne zagrożenie dla bezpieczeństwa danych organizacji oraz jej infrastruktury.
Recommendation
Zaleca się aktualizację Skyvern do najnowszej wersji, aby usunąć tę podatność oraz wdrożenie dodatkowych mechanizmów zabezpieczających, takich jak filtrowanie i walidacja danych wejściowych.

Original NVD description (English source)
Skyvern through 0.1.85 is vulnerable to server-side template injection (SSTI) in the Prompt field of workflow blocks such as the Navigation v2 Block. Improper sanitization of Jinja2 template input allows authenticated users to inject crafted expressions that are evaluated on the server, leading to blind remote code execution (RCE).
