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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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 3 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 3 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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 OS Recovery tool to 2.4.4.

AI-suggested

Upgrade the Dell OS Recovery tool to version 2.4.4 or later, where this vulnerability has been fixed. No other mitigation actions are indicated by the vendor advisory.

Description

Dell OS Recovery tool versions prior to 2.4.4 contain a vulnerability involving the use of a hard-coded cryptographic key. This flaw could allow an unauthenticated attacker with physical access to the device to potentially disclose sensitive information. The vulnerability is addressed in version 2.4.4.

Impact

An unauthenticated attacker with physical access to a device running a vulnerable version of the Dell OS Recovery tool could exploit the hard-coded cryptographic key vulnerability to disclose information. The impact is limited to confidentiality, with no integrity or availability effects reported. The overall severity is low.

Summary

CVE-2026-82154 identifies a CWE-321 vulnerability in Dell OS Recovery tool versions before 2.4.4, where a hard-coded cryptographic key is used. This cryptographic weakness could be exploited by an attacker who has physical access to the affected system, potentially leading to information disclosure. The vulnerability does not require user interaction or privileges and has a low CVSS score of 2.4, reflecting limited impact and exploitability. Dell fixed this issue in version 2.4.4.
