Severity by source
AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H
Aligns with vendor vector: high privileges and complexity constrain exploitation; C/I/A:H reflect full file system impact within scope.

Tanium addressed a path traversal vulnerability in Tanium Data Service.
AnalysisAI
Path traversal in Tanium Data Service 4.2 prior to build 4.2.345 allows a highly privileged, remote-authenticated attacker to read, write, or otherwise manipulate files outside the application's intended directory scope. Tanium addressed this in their security advisory TAN-2026-044 with a patch to build 4.2.345. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) network access to the Tanium Data Service (AV:N), (2) a highly privileged account or session within the Tanium platform (PR:H) - standard end-user or read-only credentials are insufficient, and (3) high attack complexity conditions (AC:H), implying additional prerequisites such as specific service state, race conditions, or configuration that are not detailed in the sparse vendor description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.6 reflects a meaningful tension in the vector metrics: impact is maximal (C:H/I:H/A:H), suggesting potential for full file system compromise within scope, but this is substantially constrained by AC:H (high attack complexity) and PR:H (high privileges required). … 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 | Upgrade Tanium Data Service to build 4.2.345 or later per Tanium security advisory TAN-2026-044 (https://security.tanium.com/TAN-2026-044). … Detailed patch versions, workarounds, and compensating controls in full report. |
