Confidentiality: None
Integrity: None
Availability: High

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 22 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed

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.

What to do

Upgrade PowerScale OneFS to 9.13.0.0, 9.10.1.4, 9.7.1.11 or 9.5.1.6; dell/powerscale-onefs to 9.13.0.0.

AI-suggested

1. Restrict local access to Dell PowerScale OneFS systems strictly to trusted and authenticated personnel to minimize the risk of exploitation. 2. Implement robust user account management and monitoring to detect and prevent unauthorized local user activity. 3. Apply principle of least privilege rigorously to all local accounts to reduce the potential impact of permission misconfigurations. 4. Monitor system logs for unusual activities that could indicate attempts to exploit permission weaknesses. 5. 6. Consider deploying additional endpoint security controls on systems with local access to detect and block suspicious actions. 7. Conduct internal audits of permission settings on critical resources within OneFS to identify and remediate any misconfigurations proactively. 8. Educate local users about the risks of interacting with untrusted processes or files that could trigger exploitation.

Description

Dell PowerScale OneFS, versions 9.5.0.0 through 9.5.1.5, versions 9.6.0.0 through 9.7.1.10, versions 9.8.0.0 through 9.10.1.3, versions starting from 9.11.0.0 and prior to 9.13.0.0, contains an incorrect permission assignment for critical resource vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to denial of service.

Impact

For European organizations, the primary impact of CVE-2026-22280 is the potential for denial of service on Dell PowerScale OneFS storage systems. This can disrupt access to critical data and storage services, affecting business continuity, especially in sectors relying heavily on high-availability storage such as finance, healthcare, and manufacturing. Since the vulnerability requires local access and user interaction, insider threats or compromised internal accounts pose the greatest risk. The lack of impact on confidentiality and integrity reduces the risk of data breaches but does not eliminate operational risks. Organizations with extensive deployments of Dell PowerScale OneFS may face service interruptions, impacting productivity and potentially causing financial losses. The absence of known exploits in the wild reduces immediate risk but does not preclude targeted attacks, especially in environments with less stringent internal access controls.

CWE-732Incorrect Permission Assignment for Critical Resource (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
Implementation
When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
