CVE-2026-42822, Microsoft Azure Local Disconnected Operations (ALDO): CVSS 10.0 unauthenticated network elevation-of-privilege, "Exploitation More Likely"

Microsoft assigned CVE-2026-42822 (CVSS 3.1 = 10.0, CWE-287 Improper Authentication, vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) to an authentication-bypass flaw in Azure Local Disconnected Operations (ALDO) (Microsoft's solution for running Azure services in air-gapped or partially-disconnected infrastructure environments) that allows an unauthorised network attacker to elevate privileges over a network with no credentials and no prior foothold (Microsoft MSRC, 2026-05-18). MSRC rates "Exploitation More Likely"; no in-the-wild exploitation observed and no public PoC at advisory release. Cloud-managed Azure customers using Microsoft-operated Resource Manager environments are already protected; only manually-operated air-gapped Azure Local stacks need action. Remediation requires upgrading ALDO to version 2604 or later via the standard ALDO update channel.
