CVE-2026-6408Network attack vector

Credential disclosure via privileged downloader retrieval

Published Apr 22, 2026 · Updated Apr 22, 2026

Credential exposure in affected Tanium Server releases allows remote authenticated users to retrieve remote source download credentials. The privileged Downloader Authentication retrieval path returns stored credentials for remote source downloads, although Tanium has not disclosed the responsible endpoint or missing safeguard. Reachability requires the Administrator role or Write Downloader Authentication permission, and the bounded impact is disclosure of those credentials.
