MariaDB: Mehrere Schwachstellen
WID-SEC-2026-4018 · first 19.10.2026 · updated 26.10.2026 · CVSS 9,9
What it is about
MariaDB ist ein relationales Datenbanksystem, das anwendungskompatibel mit MySQL ist. Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in MariaDB ausnutzen, um beliebigen Programmcode auszuführen, SQL-Injection durchzuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren oder offenzulegen oder einen Denial-of-Service-Zustand auszulösen.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
- SQL-Injection durchzuführen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren oder offenzulegen oder einen Denial-of-Service-Zustand auszulösen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- MariaDB MariaDB <13.0.2
- MariaDB MariaDB <12.3.3
- MariaDB MariaDB <11.8.9
- MariaDB MariaDB <11.4.13
- MariaDB MariaDB <10.11.19
- MariaDB MariaDB <10.6.28
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- MariaDB MariaDB 13.0.2
- MariaDB MariaDB 12.3.3
- MariaDB MariaDB 11.8.9
- MariaDB MariaDB 11.4.13
- MariaDB MariaDB 10.11.19
- MariaDB MariaDB 10.6.28
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
