Privilege escalation via Worker event token exposure
Published Jul 27, 2026 · Updated Jul 27, 2026
Information exposure in JFrog Artifactory allows remote authenticated users to obtain privileged authorization material through Worker events. JFrog has not published which event handler discloses the Worker event token or the exact operation that exposes it. Low-privileged Artifactory access is required; the exposed token enables actions with the token's higher privileges.
