Artifactory flaws chained in attacks deploying backdoor malware

Threat actors are exploiting critical and high-severity vulnerabilities in JFrog Artifactory to bypass authentication, gain administrative privileges, and deploy a Rust backdoor on vulnerable self-hosted servers.

A new report from cloud security company Wiz confirmed exploitation across multiple environments, including an exploit chain that combines CVE-2026-42018 and CVE-2026-42016.

The third vulnerability is CVE-2026-82329, a critical authentication bypass that offensive security company watchTowr observed being exploited earlier this month to mint administrator tokens.
