CVE-2025-29972Public exploitNetwork attack vector

Tenant storage compromise via metadata-fetch DNS rebinding

Published May 8, 2025 · Updated Feb 26, 2026

Server-side request forgery in Microsoft Azure Storage Resource Provider allows remote authenticated users to spoof service requests. A DNS-rebinding sequence hijacks the service's identity-metadata fetch, causing it to follow an attacker-directed endpoint and expose Microsoft Entra ID tokens for arbitrary tenants. An Azure-authorized attacker can abuse a leaked token to move across tenants and regenerate SFTP passwords, compromising tenant storage.
