CVE-2025-15338Network attack vector

Platform-wide read-write access via overbroad default permissions

Published Feb 5, 2026 · Updated Feb 5, 2026

Incorrect default permissions in Tanium Partner Integration allow remote authenticated users to read and write all platform content. The service grants the Partner Integration Service Account permission platform-wide read and write authority instead of limiting it to integration resources. Exploitation requires an authenticated Tanium account holding that permission; no availability impact is reported.
