CVE-2026-65616Network attack vector

Administrator privilege escalation via refresh-token signature validation

Published Jul 27, 2026 · Updated Jul 27, 2026

Improper signature verification in JFrog Artifactory before 7.146.27 allows remote authenticated users to obtain administrator tokens. Artifactory's refresh-token validation accepts a non-admin user's token in a way that causes the service to sign and return a JFrog administrator token. A non-admin account and network access are required; the resulting token grants administrator privileges over the repository service.
