Microsoft Purview Data Governance is affected by a critical SSRF vulnerability that enables unauthenticated attackers to elevate privileges over the network.

This vulnerability is a Server-Side Request Forgery (CWE-918) within the Data Quality component. It allows an unauthorized attacker to trick the server into making requests to internal or external resources, which can be leveraged to escalate privileges.

The CVSS score of 10.0 highlights the extreme risk associated with this flaw. Successful exploitation allows an attacker to bypass internal network protections, potentially gaining access to internal data, services, or administrative functions that are intended to be shielded from the public internet.

Immediate Action: Navigate to the Microsoft Security Response Center update guide and apply the latest security updates for Microsoft Purview Data Governance.

Proactive Monitoring: Monitor server logs for unusual outbound requests from the Purview environment to internal or sensitive external IP addresses.

Compensating Controls: Implement egress filtering on the network level to prevent the server from reaching unauthorized internal or external endpoints.

Public Exploit Available: No (unknown)

Due to the critical nature of this SSRF vulnerability, organizations must treat this as an urgent security update. Apply the vendor patches as soon as they become available and review internal network segmentation to minimize the blast radius of any potential SSRF-based attacks.
