What it is about
Open Source vLLM ist eine Open-Source-Bibliothek für schnelle und effiziente Inferenz von Large Language Models (LLMs). Ein Angreifer kann mehrere Schwachstellen in vllm ausnutzen, um Informationen offenzulegen, Daten zu manipulieren, Sicherheitsmaßnahmen zu umgehen oder einen Denial-of-Service-Zustand herbeizuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- Informationen offenzulegen
- Daten zu manipulieren
- Sicherheitsmaßnahmen zu umgehen oder einen Denial-of-Service-Zustand herbeizuführen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Open Source vllm <0.26.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source vllm 0.26.0
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.
