Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Sep 2025
Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should prioritize the following specific actions: 1) Immediately verify the version of StorageGRID in use and plan for an upgrade to versions 11.8.0.15 or 11.9.0.8 or later once patches are available from NetApp. 2) Restrict and audit user privileges rigorously to ensure that only necessary personnel have authenticated access, minimizing the risk of privilege escalation. 3) Implement network segmentation and access controls to limit exposure of StorageGRID management interfaces and internal nodes, reducing the attack surface. 4) Monitor logs and alerts for unusual access patterns or attempts to enumerate Grid nodes or modify configurations. 5) Employ multi-factor authentication (MFA) for all StorageGRID access to reduce the risk of credential compromise. 6) Engage with NetApp support for any interim mitigation guidance or configuration hardening recommendations. 7) Conduct internal penetration testing focused on privilege escalation scenarios within StorageGRID environments to identify and remediate potential exploitation paths.

Description

StorageGRID (formerly StorageGRID Webscale) versions prior to 11.8.0.15 and 11.9.0.8 are susceptible to a privilege escalation vulnerability. Successful exploit could allow an unauthorized authenticated attacker to discover Grid node names and IP addresses or modify Storage Grades.

Impact

For European organizations relying on NetApp StorageGRID for critical data storage and management, this vulnerability poses a significant risk to data confidentiality and integrity. Unauthorized disclosure of Grid node names and IP addresses could facilitate further targeted attacks, reconnaissance, or lateral movement within the network. Modification capabilities could lead to data tampering or disruption of storage services, potentially affecting business operations, compliance with data protection regulations such as GDPR, and customer trust. Given that StorageGRID is often deployed in sectors with stringent data security requirements (e.g., finance, healthcare, government), exploitation could result in regulatory penalties and reputational damage. The medium severity and requirement for authenticated access somewhat limit the threat scope; however, insider threats or compromised credentials could be leveraged by attackers to exploit this vulnerability. The lack of current known exploits suggests a window for proactive mitigation before widespread exploitation occurs.

CWE-266Incorrect Privilege Assignment (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
