Severity by source
AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:L
Network-reachable, low-complexity file write; PR:L reflects credential gate; S:C and I:H capture host-escaping write; C:N because no read impact is described.
Primary rating from Vendor (Tanium).

Tanium addressed a path traversal vulnerability in Comply.
AnalysisAI
Path traversal in Tanium Comply exposes all authenticated low-privilege users to a scope-changing arbitrary file write against the underlying host. The CVSS vector (AV:N/AC:L/PR:L/S:C/I:H) confirms the vulnerability is network-reachable without administrative credentials and breaks containment boundaries beyond the Comply module itself. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Tanium Comply user account with at minimum low-privilege access (PR:L per the CVSS vector); unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.5 (High) score is driven primarily by the scope change and high integrity impact rather than confidentiality exposure, which is rated None. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-supplied fix referenced in Tanium security advisory TAN-2026-043 at https://security.tanium.com/TAN-2026-043. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict Tanium Comply module access to administrative users only through role-based access controls and audit all low-privilege account activities for unauthorized file operations. …
