Miggo AIRoot Cause Analysis

The provided vulnerability information describes an improper API group specification in Kubernetes RBAC resource creation, but does not include specific code references, commit diffs, or function names. While the root cause appears to be in RBAC rule generation logic (particularly around setting apiGroup fields), the available data sources (CVE, GHSA, and related issues) do not explicitly identify vulnerable function names or file paths. The vulnerability likely exists in Rancher's role template handling or RBAC resource generation code, but without concrete code examples or patch details, specific functions cannot be identified with high confidence.
