WID-SEC-2026-3066 · first 28.08.2026 · updated 17.09.2026 · CVSS 8,1
What it is about
MongoDB ist ein Open-Source-Dokumentendatenbank. Ein Angreifer kann mehrere Schwachstellen in verschiedenen MongoDB Clients ausnutzen, um Sicherheitsvorkehrungen zu umgehen, vertrauliche Informationen offenzulegen, Daten zu manipulieren oder Denial-of-Service-Zustände 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
- Sicherheitsvorkehrungen zu umgehen
- vertrauliche Informationen offenzulegen
- Daten zu manipulieren oder Denial-of-Service-Zustände herbeizuführen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Fedora Linux
- SUSE openSUSE
- Open Source MongoDB BI Connector <2.14.30
- Open Source MongoDB GO Driver <2.8.2
- Open Source MongoDB C++ Driver <4.5.1
- Open Source MongoDB libmongocrypt <1.20.3
- Open Source MongoDB C Driver <2.5.1
- Open Source MongoDB PHP Library <2.4.1
- Open Source MongoDB PHP Library <1.21.4
- Open Source MongoDB Rust Driver <3.8.2
- Open Source MongoDB C# Driver <3.11.1
and 2 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source MongoDB BI Connector 2.14.30
- Open Source MongoDB GO Driver 2.8.2
- Open Source MongoDB C++ Driver 4.5.1
- Open Source MongoDB libmongocrypt 1.20.3
