Tanium addressed an information disclosure vulnerability in Tanium Server.
AnalysisAI
Authenticated information disclosure in Tanium Server across three supported release branches (7.7.3, 7.8.2, and 7.8.4) allows a low-privilege network user to access data they are not authorized to view, as described in vendor advisory TAN-2026-033. The CVSS 4.3 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) confirms the flaw is network-reachable, low-complexity, and requires only standard credentials with no user interaction. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid Tanium Server account with at minimum low-privilege access (PR:L per the CVSS vector); unauthenticated remote exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 score is consistent with a low-severity, authenticated disclosure path: network-accessible (AV:N), low complexity (AC:L), limited to low-privilege accounts (PR:L), and with only partial confidentiality impact (C:L). … 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 to the vendor-patched builds: Tanium Server 7.7.3.8298 or later (for the 7.7.3 branch), 7.8.2.1198 or later (for the 7.8.2 branch), or 7.8.4.1327 or later (for the 7.8.4 branch). … Detailed patch versions, workarounds, and compensating controls in full report. |
