WID-SEC-2026-2711 · first 10.08.2026 · updated 21.08.2026 · CVSS 8,4
What it is about
IBM DB2 ist ein relationales Datenbanksystem (RDBS) von IBM. Ein Angreifer kann mehrere Schwachstellen in IBM DB2 ausnutzen, um beliebigen Programmcode auszuführen, um seine Privilegien zu erhöhen, um Sicherheitsvorkehrungen zu umgehen, um einen Denial of Service Angriff durchzuführen, und um Informationen offenzulegen.
Under what conditions?
The BSI does not name any particular preconditions.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
- seine Privilegien zu erhöhen
- Sicherheitsvorkehrungen zu umgehen
- einen Denial of Service Angriff durchzuführen
- Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- IBM DB2 <11.5.9 Security Update #87984
- IBM DB2 <12.1.4 Security Update #86025
- IBM DB2 <12.1.5 Security Update #88454
- IBM DB2 <12.1.4 Security Update #87349
- IBM License Metric Tool 9.2.0-9.2.44.1
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- IBM DB2 11.5.9 Security Update #87984
- IBM DB2 12.1.4 Security Update #86025
- IBM DB2 12.1.5 Security Update #88454
- IBM DB2 12.1.4 Security Update #87349
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.
