CVE-2026-84731
Pre-Authentication Admin Bypass and Remote Code Execution in Nutanix Prism Gateway inside AOS
Published Oct 15, 2026 · updated Oct 15, 2026 · Nutanix Acropolis Operating System (AOS)
An unauthenticated remote attacker can bypass authentication and gain full access to administrative API endpoints in Nutanix Prism Element by including a crafted internal management HTTP header. The vulnerability is caused by a misconfiguration in the application's authentication filters. Consequently, the server responds with a Set-Cookie header containing a valid JSESSIONID. This session cookie decodes to a JSON Web Token (JWT) granting maximum cluster administrative privileges. Successful exploitation allows the attacker to execute root-level commands on all Controller VMs (CVMs) in the cluster, leading to complete cluster destruction and unauthorized access to VM memory and virtual disks.
