MariaDB Connectors: Mehrere Schwachstellen
WID-SEC-2026-3089 · first 31.08.2026 · updated 16.10.2026 · CVSS 6,5
What it is about
MariaDB ist ein relationales Datenbanksystem, das anwendungskompatibel mit MySQL ist. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in MariaDB Connectors ausnutzen, um SQL-Injection-Angriffe durchzuführen, Sicherheitsmaßnahmen zu umgehen und Daten offenzulegen oder zu manipulieren.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- SQL-Injection-Angriffe durchzuführen
- Sicherheitsmaßnahmen zu umgehen
- Daten offenzulegen oder zu manipulieren
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- MariaDB MariaDB Connector/Node.js <3.5.4
- MariaDB MariaDB Connector/J <3.5.10
- MariaDB MariaDB Connector/R2DBC <1.4.1
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- MariaDB MariaDB Connector/Node.js 3.5.4
- MariaDB MariaDB Connector/J 3.5.10
- MariaDB MariaDB Connector/R2DBC 1.4.1
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.
