WID-SEC-2026-0813 · first 23.03.2026 · updated 23.03.2026 · CVSS 5,3
What it is about
PyTorch ist eine Tensor-Bibliothek für Deep Learning mit GPUs und CPUs. Ein lokaler Angreifer kann eine Schwachstelle in PyTorch ausnutzen, um beliebigen Programmcode auszuführen.
Under what conditions?
Only with access to the device or an account on it. Often the second step after a phishing email.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
Am I affected?
Affected according to the BSI:
- Open Source PyTorch 2.10.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Install the updates provided by the vendor; details in the sources below.
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.
