Attack-Flow Graph

Executive Summary

CVE-2026-87088 is an unauthorized code execution vulnerability in Tanium Enforce. It allows an attacker with access to a system running the Tanium Client to escalate privileges locally if a maliciously-named file in antivirus quarantine is processed during a remediation action.

Detection Guidance

Detection involves checking Tanium Enforce versions against affected releases. Verify installed versions with commands like 'tanium-enforce --version' or checking update logs. Inspect quarantined files for suspicious names that could trigger exploitation during remediation actions.

Impact Analysis

This vulnerability could allow attackers to execute arbitrary code on affected systems with elevated privileges, potentially leading to full system compromise, data theft, or further network infiltration if the attacker gains local access.

Compliance Impact

The vulnerability could allow unauthorized code execution, potentially leading to data breaches or unauthorized access to sensitive information. This may impact compliance with standards like GDPR or HIPAA by increasing the risk of data exposure or unauthorized processing of personal or health data.

Mitigation Strategies

Update Enforce to the latest version: Update 24 (v2.9.718) or later for 2025H1, Update 14 (v2.10.760) or later for 2025H2, or Update 7 (v3.0.346) or later for 2026H1. No other mitigations are provided.
