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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:60404** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.11 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60404)\n- **RHSA-2026:60403** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.13 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60403)\n- **RHSA-2026:60401** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.14 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60401)\n- **RHSA-2026:60402** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.15 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60402)\n- **RHSA-2026:60400** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.16 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60400)\n- **RHSA-2026:60399** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.17 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60399)","depth":"twilight","depthScore":44,"depthScoreParts":{"impact":44,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
