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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: 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.

CVE published 5 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: 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 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 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 Interact to 3.5.90, 3.2.185 or 3.1.337.

AI-suggested

1. 2. Restrict network access to Tanium Interact interfaces using firewalls, VPNs, or network segmentation to limit exposure to trusted administrators only. 3. Implement strict role-based access controls (RBAC) within Tanium to minimize privileges granted to users and service accounts. 4. Monitor Tanium Interact logs and network traffic for unusual access patterns or unauthorized queries that could indicate exploitation attempts. 5. Conduct regular security audits and penetration tests focusing on authorization mechanisms in endpoint management tools. 6. Educate security teams about this vulnerability to ensure rapid detection and response. 7. Maintain an inventory of Tanium Interact deployments and versions across the organization to prioritize remediation efforts effectively.

Description

Tanium addressed an improper access controls vulnerability in Interact.

Impact

For European organizations, the primary impact of CVE-2025-15289 is a limited confidentiality breach, potentially exposing sensitive endpoint management data to unauthorized users with low privileges. While the vulnerability does not affect system integrity or availability, unauthorized data access could aid attackers in reconnaissance or lateral movement within networks. Organizations relying on Tanium Interact for security operations may face increased risk if attackers leverage this flaw to gather intelligence on endpoints or configurations. The high attack complexity and requirement for low privileges reduce the likelihood of widespread exploitation, but targeted attacks against critical infrastructure or sensitive sectors remain a concern. Failure to address this vulnerability could undermine trust in endpoint management security and compliance with data protection regulations such as GDPR.
