External risk briefCRITICAL

CVE-2026-42823

Halo Surface Signal

3/ 5

The vulnerability resides in Azure Logic Apps, a cloud-hosted service accessible via the internet. While it is a web-based platform, the flaw requires an already authorized user to trigger the privilege escalation, placing the affected logic behind the provider's authentication layer rather than being directly exposed as an unauthenticated public entry point.

Exposure facts

H – Horizon Alert

A security vulnerability has been identified in Azure Logic Apps involving improper access controls. This issue could allow an already authorized user to gain elevated privileges within the network environment. Consequently, there is a risk that individuals could access system functions or data that exceed their intended permissions.

A – Asset Exposure

This issue affects Azure Logic Apps, which are used to orchestrate automated workflows across various systems. If an already authorized entity takes advantage of this flaw, they could potentially elevate their privileges beyond their intended permissions. This may allow them to gain unauthorized control over automated processes, access sensitive business data, or manage service configurations they are not otherwise authorized to modify. As a cloud-native service, these workflows are typically accessible over a network by authenticated users, making effective identity and access management a critical defense.
