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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

1. Restrict remote access to Dell PowerProtect Data Domain systems strictly to trusted administrators and secure management networks using network segmentation and firewalls. 2. Implement strong multi-factor authentication (MFA) for all privileged accounts to reduce the risk of credential compromise. 3. Monitor and audit privileged user activities and remote access logs to detect unusual or unauthorized behavior promptly. 4. 5. Employ encryption for data at rest and in transit within backup environments to minimize the impact of any potential information disclosure. 6. Conduct regular security assessments and penetration testing focusing on backup infrastructure to identify and remediate privilege escalation or remote access weaknesses. 7. Limit the number of high privileged accounts and enforce the principle of least privilege to reduce the attack surface.

Description

Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 7.7.1.0 through 8.4.0.0, LTS2025 release version 8.3.1.10, LTS2024 release versions 7.13.1.0 through 7.13.1.40, LTS 2023 release versions 7.10.1.0 through 7.10.1.70, contain an Exposure of Sensitive Information to an Unauthorized Actor vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Information disclosure.

Impact

For European organizations, the primary impact of CVE-2025-46676 is the potential unauthorized disclosure of sensitive information stored or processed by Dell PowerProtect Data Domain systems. These systems are widely used in enterprise environments for backup and disaster recovery, often containing critical business and personal data. Exposure of such information could lead to data privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. Although the vulnerability requires high privileged remote access, if an attacker compromises administrative credentials or exploits other vulnerabilities to gain such access, they could leverage this flaw to extract sensitive data. This risk is particularly relevant for sectors with stringent data protection requirements, including finance, healthcare, and government agencies. The limited severity score suggests the threat is not critical but still warrants attention due to the sensitive nature of the data involved and the potential cascading effects of information disclosure.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #20OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
