Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Tanium addressed an arbitrary file deletion vulnerability in TanOS.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-07-30.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Recommended fix High confidence

Upgrade to TanOS 1.8.4.0229 or later (1.8.4 branch) or 1.8.5.0262 or later (1.8.5 branch); prefer latest 1.8.5.x stable release

  1. 1. Identify the current TanOS version installed by checking the Tanium server or endpoint configuration
  2. 2. If running version 1.8.4.x (between 1.8.4.0000 and 1.8.4.0228), plan upgrade to version 1.8.4.0229 or later
  3. 3. If running version 1.8.5.x (between 1.8.5.0000 and 1.8.5.0261), plan upgrade to version 1.8.5.0262 or later
  4. 4. Review Tanium upgrade documentation and release notes for prerequisites
  5. 5. Schedule maintenance window as upgrades may require endpoint restart
  6. 6. Perform upgrade following Tanium standard upgrade procedures
  7. 7. Verify successful upgrade by checking the new TanOS version post-installation
  8. 8. Validate that the arbitrary file deletion vulnerability is remediated
Caveat Standard Tanium upgrade considerations apply - review release notes for any configuration or behavioral changes between versions
