In 3.0.1-4-ge2626659, Microsoft UFO&#8217;s constellation client tracks pending task responses by session_id only and does not verify that a TASK_END message came from the device that originally received the task. When the constellation sends a task to a target device, it records a pending Future under a session key. The pending task record stores the expected device ID, but the completion path ignores that binding. If another authenticated peer device sends a forged TASK_END with the same session_id, the constellation accepts the response and completes the victim device&#8217;s pending Future with attacker-controlled result data. This is an authenticated cross-device task-result injection issue.<\/p>\n<p>  Severity: 5.9 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-46538 Published : May 27, 2026, 11:16 p.m. | 1\u00a0hour, 15\u00a0minutes ago Description :Microsoft UFO open-source framework for intelligent automation across devices and platforms.
