CVE-2026-42822 is a maximum-severity improper authentication vulnerability in Microsoft Azure Local Disconnected Operations (ALDO). The flaw allows an unauthorized attacker to bypass intended authentication controls over the network and elevate privileges within the affected environment. Publicly available information does not disclose the exact failing authentication flow, protocol exchange, or vulnerable code path, but the issue is characterized as an authentication bypass leading directly to privilege escalation. The vulnerability affects ALDO versions prior to 2604.2.25645, including version 1.0.0 through builds before that patched release. The CVSS 3.1 vector indicates network reachability, low attack complexity, no required privileges, no user interaction, and changed scope, with high impact to confidentiality, integrity, and availability.
