## Technical details

The vulnerability is an improper access controls flaw in Tanium Comply that fails to properly validate authorization boundaries for scan execution. An authenticated attacker with the "Comply Report Write" and "Comply Scan Execute" permissions can execute scans against endpoints beyond their assigned management scope. The attack requires valid Tanium credentials and the specific permissions noted, but no user interaction. Exploitation allows unauthorized scanning of systems the attacker lacks management rights over. Patches are available for all supported release branches: v2.32.252+, v2.35.306+, and v2.37.308+.
