CVE-2025-56798 · Severity: high · CVSS 8.8 · Published 2026-08-26

Unraid is a web-managed hypervisor system that stores virtual machines, containers, and data on home and small business servers. A flaw in the authentication cookie configuration allows attackers on the same network to forge requests that chain with cross-site scripting vulnerabilities to gain root access to the entire hypervisor system, compromising all hosted services and data.

## Technical details

The vulnerability stems from the Unraid authentication cookie (unraid_<HEX>) lacking an explicit SameSite attribute, defaulting to Lax mode, which permits the cookie to be sent on top-level navigations initiated by third-party sites. Combined with the absence of an Expires attribute (Session-only), attackers can chain CSRF with reflected and stored XSS vulnerabilities in multiple web UI input fields (device name, share browser path, server/user/folder comments) to trigger malicious JavaScript execution within an authenticated user's browser. An attacker on the local network can craft a drive-by attack leveraging common Unraid hostname patterns, and if a victim visits a malicious website while maintaining an active Unraid session, the attacker can install a malicious plugin that executes arbitrary shell commands with root privileges, achieving persistent code execution and full hypervisor takeover. The Unraid team has patched these vulnerabilities; users should upgrade to version 6.12.15 or later.
