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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:59636** · Red Hat · fixed in: multicluster engine for Kubernetes 2.11 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59636)\n- **RHSA-2026:59634** · Red Hat · fixed in: multicluster engine for Kubernetes 2.17 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59634)\n- **RHSA-2026:59637** · Red Hat · fixed in: multicluster engine for Kubernetes 2.1 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59637)\n- **RHSA-2026:59643** · Red Hat · fixed in: multicluster engine for Kubernetes 2.6 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59643)\n- **RHSA-2026:59642** · Red Hat · fixed in: multicluster engine for Kubernetes 2.8 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59642)\n- **RHSA-2026:59638** · Red Hat · fixed in: multicluster engine for Kubernetes 2.9 · released 2026-08-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:59638)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":42.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
