CVE-2026-12977— Org.wildfly.core/wildfly-server: wildfly: rbac bypass in wildfly deployment-operation handlers leads to privilege escalation

Quick assessment

Affected

Red Hat Red Hat Fuse 7

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 WildFly Core 的部署操作（deployment-operation）系列中发现了缺陷：某些处理器（例如 upload-deployment-url）缺乏适当的敏感度分类，导致拥有受限“维护者（Maintainer）”角色的管理员能够读取敏感配置文件。这可能引发凭据泄露，并导致攻击者获得服务器的完全管理员控制权（SuperUser）。

Vulnerability Title

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

Source: CVE Program / CVE List V5

Vulnerability 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.
