# Entra Device Registration: authorization bypass lets attacker elevate privileges over network

Link for people: https://infrastack.ai/live/CVE-2026-109469 (this .md is for agents)

Microsoft Entra Device Registration trusts a user-controlled key, which lets an unauthorized attacker bypass authorization. Per the NVD description, the attacker can elevate privileges over the network.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

unknown: Microsoft has not published checkable details I could read. Entra Device Registration is a cloud service, so check the MSRC Security Update Guide entry for CVE-2026-109469 for whether Microsoft fixed it service-side and whether customers must act.

## Timeline

- 2026-11-06T23:44:35+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-109469
- 2026-11-06T23:45:49+00:00 analyst — MSRC page is JS-only (empty via web-cli) and CVRF API returned no CVE content; only NVD text (CVSS 10.0, AV:N/PR:N, scope changed) and a third-party mirror (Entra Device Registration, no known exploitation) available. Affected versions, cloud-side fix status, required privileges unconfirmed; nothing verified. Revisit with browser-cli on MSRC or when Microsoft's advisory text is indexed.

## From the sources

Authorization bypass through user-controlled key in Entra Device Registration allows an unauthorized attacker to elevate privileges over a network.
