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 22 Apr 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 29 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.
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 Tanium Threat Response to 4.9.379 or 4.6.577.

Affected software

Product	Affected	Fixed in
TaniumThreat Response	Affected >=4.9.0 <4.9.379	Fixed in 4.9.379
TaniumThreat Response	Affected >=4.6.0 <4.6.577	Fixed in 4.6.577

AI-suggested

Given the high privilege requirement, restricting access to the affected versions and ensuring proper privilege management may reduce risk.

Description

CVE-2026-6392 is an information disclosure vulnerability in Tanium Threat Response versions 4.6.0 and 4.9.0. The vulnerability allows exposure of sensitive information to unauthorized actors. The CVSS score is low (2.7), indicating limited impact. No known exploits are reported in the wild.

Impact

The impact is limited to a low confidentiality loss of sensitive information. There is no impact on integrity or availability. Exploitation requires high privileges, reducing the likelihood of unauthorized access by low-privileged users. No known active exploitation has been reported.

Summary

This vulnerability in Tanium Threat Response involves unauthorized exposure of sensitive information. It affects versions 4.6.0 and 4.9.0. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, and low confidentiality impact. No integrity or availability impacts are noted.
