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.

Red Hat Product Security has rated this vulnerability as having an Important impact. While it requires existing administrative privileges (Maintainer role), it allows for a complete bypass of the RBAC framework, leading to full privilege escalation to SuperUser. This enables an attacker to perform any action on the server, including deploying malicious code or mutating audit logs. Red Hat would like to thank Kelvin Mbogo for reporting this issue. Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
