## Technical details

The vulnerability is an improper access controls flaw in Tanium Comply that fails to properly validate content set ownership when handling credential operations. An authenticated user with the Comply Credential Write permission can create or modify credentials belonging to a different content set than their own, bypassing intended access restrictions. The attack requires valid authentication and the target permission but no user interaction. Exploitation allows credential hijacking and lateral movement across different organizational contexts. Patches are available for all affected release lines: v2.32.252 (2025H1), v2.35.306 (2025H2), and v2.37.308 (2026H1).
