CVE-2026-32710
HighSummary
Serwer MariaDB, będący rozwidleniem serwera MySQL, ma błąd w funkcji JSON_SCHEMA_VALID(), który pozwala uwierzytelnionemu użytkownikowi na awarię wersji 11.4 przed 11.4.10 oraz 11.8 przed 11.8.6. W określonych warunkach możliwe jest przekształcenie tej awarii w zdalne wykonanie kodu.
Risk Assessment
Organizacja może być narażona na poważne ryzyko, w tym potencjalne zdalne wykonanie kodu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem. Wymaga to jednak specyficznych warunków, które są trudne do osiągnięcia poza środowiskiem laboratoryjnym.
Recommendation
Zaleca się aktualizację do wersji MariaDB 11.4.10, 11.8.6 lub 12.2.2, aby usunąć tę podatność. Należy również monitorować dostęp do serwera i wprowadzić dodatkowe środki bezpieczeństwa dla uwierzytelnionych użytkowników.

Original NVD description (English source)
MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSON_SCHEMA_VALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.
