CVE-2026-35428 is a critical command injection vulnerability in Azure Cloud Shell caused by improper neutralization of special elements used in a command. The flaw stems from insufficient handling of user-supplied input processed by the hosted Cloud Shell service, creating a condition in which crafted input could influence command execution behavior. Microsoft classifies the issue as a spoofing vulnerability in impact terms, and the published CVSS v3.1 vector is AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H. Azure Cloud Shell is an exclusively hosted Microsoft-managed service, so the vulnerable component resided in backend service infrastructure rather than customer-managed software installations.
