CVE-2025-15322Network attack vector

Restricted data disclosure via Dynamic Questions authorization

Published Jan 30, 2026 · Updated Jan 30, 2026

Incorrect authorization in Tanium Server allows remote authenticated users to read restricted data through Dynamic Questions. The server fails to enforce the intended data-access boundary when processing requests from accounts holding the Ask Dynamic Questions permission; Tanium has not disclosed the affected handler or authorization check. Exploitation requires that permission and yields read-only access, with no reported ability to modify data or interrupt the service.
