CVE-2025-15330Network attack vector

Fleet-wide code execution via missing authorization

Published Feb 5, 2026 · Updated Feb 5, 2026

Missing authorization in Tanium Deploy allows remote authenticated users to execute code across all managed endpoints. Tanium has not disclosed the input-validation locus or the malformed value that permits unauthorized code execution. Exploitation requires both Deploy Deployment - Write and Deploy Software Package - Write permissions; successful use runs code on every managed endpoint in the Deploy context.
