WID-SEC-2026-4189 · first 28.10.2026 · updated 29.10.2026 · CVSS 9,6
What it is about
Python ist eine universelle, üblicherweise interpretierte, höhere Programmiersprache. Ein Angreifer kann mehrere Schwachstellen in Python ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, Sicherheitsvorkehrungen zu umgehen oder Dateien zu manipulieren.
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
- einen nicht näher spezifizierten Angriff durchzuführen
- Sicherheitsvorkehrungen zu umgehen oder Dateien zu manipulieren
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Open Source Python <3.11.18
- Open Source Python <3.12.16
- Open Source Python <3.13.18
- Open Source Python <3.14.10
- Open Source Python <3.15.2
- Open Source Python <3.16.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Python 3.11.18
- Open Source Python 3.12.16
- Open Source Python 3.13.18
- Open Source Python 3.14.10
- Open Source Python 3.15.2
- Open Source Python 3.16.0
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.
