Org.wildfly.core/wildfly-server: wildfly: rbac bypass in wildfly deployment-operation handlers leads to privilege escalation

No exploitation reported by the sources we read.

  • Published2026-11-09
  • WeaknessCWE-267

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

A flaw was found in the deployment-operation family of WildFly Core. Certain handlers, such as upload-deployment-url, lack proper sensitivity classification, allowing an administrator with the restricted "Maintainer" role to read sensitive configuration files. This can lead to the exfiltration of credentials and full administrative control (SuperUser) of the server.
