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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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 PowerProtect Data Manager to 19.22.0-24 or later.

AI-suggested

To mitigate CVE-2026-22269, organizations should prioritize applying the official patch or update from Dell as soon as it becomes available for PowerProtect Data Manager versions prior to 19.22. Until a patch is deployed, it is critical to restrict network access to the REST API interfaces by implementing strict firewall rules and network segmentation to limit exposure to trusted management networks only. Employ strong authentication and authorization controls to ensure that only authorized high-privileged users can access the management interfaces. Regularly audit and monitor access logs for unusual or unauthorized activity related to the REST API. Additionally, consider deploying intrusion detection or prevention systems (IDS/IPS) tuned to detect anomalous API requests. Conduct thorough security reviews of backup and data protection configurations to ensure no unnecessary privileges are granted. Finally, maintain an incident response plan that includes scenarios involving backup system compromise to enable rapid containment and recovery.

Description

Dell PowerProtect Data Manager, version(s) prior to 19.22, contain(s) an Improper Verification of Source of a Communication Channel vulnerability in the REST API. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to protection mechanism bypass.

Impact

The potential impact of CVE-2026-22269 includes unauthorized bypass of protection mechanisms within Dell PowerProtect Data Manager, which could lead to partial compromise of backup data confidentiality, integrity, and availability. Organizations relying on this product for critical data protection may face risks such as unauthorized data access, manipulation, or disruption of backup operations. Although exploitation requires high privileges, the vulnerability could facilitate further malicious activities by attackers who have already gained elevated access, potentially enabling lateral movement or persistence within the environment. This could undermine disaster recovery capabilities and increase the risk of data loss or corruption. The medium severity rating reflects that while the vulnerability is not trivially exploitable by low-privileged attackers, the consequences of exploitation in sensitive environments could be significant, especially in sectors where data protection is paramount such as finance, healthcare, and government.

The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.
Architecture and Design
Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.
