Service interrupt via compression bomb
Published Aug 19, 2026 · Updated Aug 20, 2026
Denial of service in Tanium Threat Response before 4.9.437, 4.12.308, and 4.17.277 allows attackers to interrupt the service via a compression bomb. Tanium has not disclosed the specific parser, file handler, or request path; the published record identifies only a compression bomb condition in Threat Response that can consume enough resources to stop the service. Reachability requires access to a system running the Tanium Client, and the published scoring bounds the outcome to availability loss rather than data disclosure or data modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=4.12 <4.12.308
- Affected versionversion=4.17 <4.17.277
- Affected versionversion=4.9 <4.9.437
