CVE-2026-113763Microsoft Windows 10 broken cryptography

Low priorityMedium6.3EPSS not scored yet

CVE-2026-113763 is a broken cryptography in Microsoft Windows 10, rated medium (6.3 on CVSS 3.1).

Why this priority: Medium severity, with no exploitation signal.

Published · Updated · NVD status: Awaiting Analysis

What it is

A broken or risky cryptographic algorithm protects sensitive data.

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. Success also depends on conditions the attacker does not fully control.

What an attacker gains

A successful attack can read the data it protects and change data or behaviour. In practice, this kind of flaw lets an attacker read or tamper with traffic, or pass a forged message as genuine.

Is it being exploited?

There is no public report of exploitation yet.

What to do

  1. Apply the update for your edition of Microsoft Windows 10. Fixed builds: Windows 10 Version 1607: 10.0.14393.9688; Windows 10 Version 1809: 10.0.17763.9487; Windows 10 Version 21H2: 10.0.19044.7846; Windows 10 Version 22H2: 10.0.19045.7846. Other affected products have their own fixed versions on this page.
  2. Limit who can run code or sign in on the hosts that run it.

Description from NVD

Use of a broken or risky cryptographic algorithm in Windows DPAPI (Data Protection Application Programming Interface) 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

  • TLS termination and service-to-service channels. The flaw sits on the network path between clients and services.
  • Signature checks. The flaw sits on the network path between clients and services.

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.
  • On the network path between clients and services. An attacker who crosses it can read or tamper with traffic, or pass a forged message as genuine.

Questions to answer about your own systems

  • Where does Microsoft Windows 10 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?
