    High [CVE-2026-66804] Authenticated SSRF via user-controlled towerHost in /ansibletower handler

    CVE-2026-66804Source published Source updated

    Improper access control in Windows Cross Device Service allows an authorized attacker to elevate privileges locally. A flaw was found in the console component.
