CVE-2026-22048 is a Server-Side Request Forgery (SSRF) vulnerability identified in NETAPP StorageGRID (formerly StorageGRID Webscale) versions prior to 11.9.0.12 and 12.0.0.4. This vulnerability specifically affects deployments where Single Sign-on (SSO) is enabled and configured to use Microsoft Entra ID (formerly Azure AD) as the identity provider (IdP). SSRF vulnerabilities allow attackers to make unauthorized requests from the vulnerable server to internal or external systems, potentially bypassing network restrictions. In this case, an authenticated attacker with low privileges can exploit the SSRF flaw to manipulate internal requests, leading to the deletion of configuration data or denial of access to some resources within the StorageGRID environment. The attack does not require user interaction, increasing its risk. The vulnerability impacts the integrity and availability of the system but does not directly compromise confidentiality. StorageGRID is a distributed object storage solution widely used for managing large-scale unstructured data, making it a critical component in many enterprise and cloud environments. The vulnerability was published on February 17, 2026, with a CVSS v3.1 score of 7.1 (High), indicating a significant security risk. No public exploits have been reported yet, but the ease of exploitation and potential impact warrant immediate attention. The vulnerability arises from improper validation of requests in the SSO integration with Microsoft Entra ID, allowing SSRF attacks that can alter or disrupt system configurations.

The primary impact of CVE-2026-22048 is on the integrity and availability of NETAPP StorageGRID systems. Successful exploitation can lead to deletion of critical configuration data, which may cause service disruptions or denial of access to stored resources. For European organizations, especially those in sectors such as finance, healthcare, telecommunications, and government, where StorageGRID is used for large-scale data storage and management, this could result in significant operational downtime and data management challenges. The disruption of storage services could affect business continuity and compliance with data protection regulations such as GDPR. Additionally, the need for authenticated access lowers the attack complexity but still poses a risk from insider threats or compromised low-privilege accounts. The lack of confidentiality impact reduces the risk of data leakage but does not diminish the operational risks posed by potential service outages or configuration tampering.

To mitigate this vulnerability, European organizations should prioritize upgrading NETAPP StorageGRID to versions 11.9.0.12 or later, or 12.0.0.4 or later, where the SSRF flaw has been addressed. If immediate upgrading is not feasible, temporarily disabling Single Sign-on integration with Microsoft Entra ID can reduce exposure. Organizations should audit and restrict low-privilege user permissions to minimize the risk of exploitation by authenticated attackers. Network segmentation and strict firewall rules should be applied to limit the StorageGRID system’s ability to make arbitrary internal or external requests. Monitoring and logging of SSO authentication activities and configuration changes can help detect potential exploitation attempts. Additionally, organizations should review their incident response plans to include scenarios involving StorageGRID service disruptions. Coordination with NETAPP support for patches and guidance is recommended. Finally, conducting penetration testing focusing on SSRF vectors in the SSO integration can identify residual risks.
