CVE-2026-85634Network attack vector

Deployer-to-SuperUser escalation via deployment-name traversal

Published Oct 15, 2026 · Updated Oct 15, 2026

Path traversal in Red Hat JBoss Enterprise Application Platform allows remote authenticated users to escalate management privileges. The wildfly-core ContentRepositoryImpl.copyExplodedContent function processes an unsanitized deployment name without checking that the destination remains inside the deployment directory. Exploitation requires the Deployer RBAC role and permits directory deletion or creation of files with attacker-controlled content outside that directory, enabling management SuperUser access.
