在 组件中发现一个安全缺陷：在镜像获取操作期间，Red Hat 订阅管理（RHSM）的身份验证令牌会被作为命令行参数传递给后台辅助进程。在允许跨用户进程检查的系统中，本地非特权攻击者可以在进程运行时查看这些命令行参数。该缺陷可能导致信息泄露，从而在令牌有效期内使攻击者未经授权访问 RHSM 资源。

Vulnerability Title
Cockpit-machines: rhsm access-token disclosure through image helper command-line arguments
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in cockpit-machines. Red Hat Subscription Management (RHSM) authentication tokens are passed as command-line arguments to background helper processes during image retrieval operations. A local, unprivileged attacker on a system permitting cross-user process inspection can view these arguments while the process is active. This flaw can lead to information disclosure, potentially allowing unauthorized access to RHSM resources within the token's validity period.
