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: 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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 2026-10-25.

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 Dell ObjectScale to 4.2.0.0.

AI-suggested

1. Restrict local access strictly to trusted and authorized personnel only, employing strong access control policies and monitoring. 2. Implement full disk encryption or file-level encryption for storage locations containing sensitive information to prevent cleartext exposure. 3. 4. Regularly audit and monitor access logs for unusual local access patterns or attempts to access sensitive files. 5. Employ endpoint security solutions that can detect and prevent unauthorized local access or privilege escalation attempts. 6. Segregate duties and minimize the number of users with local system access to reduce insider threat risks. 7. If immediate patching is not possible, consider isolating affected systems from untrusted users and networks. 8. Review and update security policies to ensure sensitive data is never stored in cleartext and enforce encryption standards for all sensitive information at rest.

Description

CVE-2026-22276 is a medium severity vulnerability affecting Dell ObjectScale and Dell ECS versions prior to 4.2.0.0 and 3.8.1.8 respectively. It involves the cleartext storage of sensitive information, allowing a low-privileged local attacker to potentially disclose confidential data without requiring user interaction. The vulnerability does not impact integrity or availability but poses a confidentiality risk. Exploitation requires local access and low privileges, limiting remote attack feasibility.

Impact

For European organizations, the primary impact is the potential unauthorized disclosure of sensitive information stored by Dell ObjectScale or ECS systems. This can compromise confidentiality of critical credentials or configuration data, which may be leveraged by attackers to escalate privileges or move laterally within enterprise environments. Sectors such as finance, healthcare, government, and critical infrastructure that rely on Dell ObjectScale for object storage are particularly at risk. The requirement for local access limits remote exploitation but insider threats or attackers who gain initial footholds could exploit this vulnerability. Data privacy regulations such as GDPR impose strict requirements on protecting sensitive data, so any breach resulting from this vulnerability could lead to regulatory penalties and reputational damage. Additionally, organizations with multi-tenant or shared environments may face increased risk if local access controls are insufficient. The vulnerability does not directly impact system availability or integrity, but the confidentiality breach could be a stepping stone for more severe attacks.

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
Implementation · System Configuration · Operation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
Implementation · System Configuration · Operation
In some systems/environments such as cloud, the use of "double encryption" (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
