CVE-2026-76139: Inclusion of Functionality from Untrusted Control Sphere in Red Hat Red Hat Advanced Cluster Management for Kubernetes 2
A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.
