Attackers Chain JFrog Artifactory Flaws to Gain Admin Control and Plant Backdoors

Attackers are chaining multiple JFrog Artifactory vulnerabilities (CVE-2026-42018, CVE-2026-42016, CVE-2026-82329) to escalate from anonymous users to administrator control on self-hosted instances. This grants them ability to plant backdoors and execute arbitrary shell commands in your build pipeline. Any organization running self-hosted Artifactory is at immediate risk of supply chain compromise.

CRITICALAdvisorySep 12, 2026

Action required

Immediately patch all self-hosted JFrog Artifactory instances to the latest patched version. Concurrently: audit admin token activity and user permission changes in the last 30 days, scan repositories for suspicious artifacts or modifications, and monitor for any shell command execution in Artifactory logs.
