W marcu 2026 Microsoft opublikował comiesięczny zestaw aktualizacji bezpieczeństwa, w ramach którego naprawiono 79 podatności, z czego 2 stanowiły publicznie ujawnione luki typu zero‑day. Aktualizacje objęły system Windows oraz usługi i produkty takie jak Microsoft Office, SQL Server, .NET, Azure czy komponenty systemowe.
Najważniejsze elementy aktualizacji
- 2 luki zero‑day:
- CVE‑2026‑21262 – luka podnoszenia uprawnień w SQL Server, umożliwiająca uzyskanie praw SQLAdmin.
- CVE‑2026‑26127 – podatność typu Denial of Service w .NET, wywoływana przez odczyt poza zakresem.
- 3 luki o krytycznym priorytecie, z czego dwie umożliwiają zdalne wykonanie kodu (RCE) w Microsoft Office, a jedna dotyczy wycieku informacji (m.in. w Excelu).
