CVE-2026-105494Microsoft aznfs untrusted search path
CVE-2026-105494 is a untrusted search path in Microsoft aznfs, rated high (7.8 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Awaiting Analysis
What it is
The software looks for files or programs in places an attacker can write to.
How it is reached
An attacker can exploit it by someone who can already run code or sign in on the machine, with an ordinary user account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker run their code inside your build or your running service.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade Microsoft aznfs to 3.0.20 or later.
- Limit who can run code or sign in on the hosts that run it.
Description from NVD
Untrusted search path in Azure NFS mount helper (aznfs) allows an authorized attacker to elevate privileges locally.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Build pipelines, dependencies and plugins. The flaw sits between third-party code and your build or runtime.
- Update channels. The flaw sits between third-party code and your build or runtime.
Trust boundaries in play
- Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
- Between third-party code and your build or runtime. An attacker who crosses it can run their code inside your build or your running service.
Questions to answer about your own systems
- Where does Microsoft aznfs run in your systems, and at which version?
- Which of those hosts also run code or users you do not fully trust?
- What can it reach once compromised: which data stores, secrets and services?
