Technical details
The vulnerability is a server-side request forgery (SSRF) flaw in Tanium Threat Response that allows authenticated users with the Threat Response Live Response Destinations Write permission to read unauthorized data. The attack requires valid authentication and the specific permission set, limiting exposure to internal or privileged users. An attacker can leverage the SSRF to access internal resources or data by manipulating server requests, compromising confidentiality without affecting system availability or integrity. Patches are available for all affected release branches: 2025H1 (Update 25 or later), 2025H2 (Update 15 or later), and 2026H1 (Update 8 or later).
