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.
