Artifactory anonymous token chain (CISA KEV)

Self-hosted JFrog Artifactory could hand an internal anonymous-user token to an unauthenticated caller even when anonymous access was disabled, opening a path into sensitive resources. CISA KEV and public in-the-wild reporting apply. Upgrade past the fixed builds for your Artifactory train and rotate credentials if exposure is plausible.

Uncertainty and limitations

Read the evidence limits before acting on this record.

Sibling CVE-2026-42016 may appear in the same advisory wave; confirm both IDs and exact fixed builds against JFrog's advisory for your installed build.

  • Covers the anonymous token / scope chain tracked under CVE-2026-42018 (and related CVE-2026-42016 context); not every Artifactory CVE.
  • CISA KEV and public in-the-wild reporting elevate urgency; rotate tokens after upgrade if exposure is suspected.
  • Fixed version list must be verified against JFrog's live advisory for your minor.
