CVE-2026-75569— Mce-operator-bundle: mce-operator-bundle: bundle-generation business logic fetched from mutable stolostron/release@master

Quick assessment

Affected
Red Hat multicluster engine for Kubernetes 2.10
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 mce-operator-bundle 中发现了一个缺陷。构建过程会从远程仓库获取并执行脚本，但未进行完整性检查（例如提交锁定或签名验证）。这使得对远程仓库具有写权限的攻击者能够在构建过程中注入并执行任意代码。其后果是构建过程被篡改，可能导致恶意软件的发布和分发。

Vulnerability Title
Mce-operator-bundle: mce-operator-bundle: bundle-generation business logic fetched from mutable stolostron/release@master
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in mce-operator-bundle. The build process fetches and executes scripts from a remote repository without performing integrity checks, such as commit pinning or signature verification. This allows a malicious actor with write access to the remote repository to inject and execute arbitrary code during the build. The consequence is a compromised build process, potentially leading to the distribution of malicious software.
