Miggo AIRoot Cause Analysis

The vulnerability stemmed from experimental annotation exposure features added in v1.7.0. The commit diff shows removal of '*_annotations' metric generators across all resource handlers. These functions directly converted Kubernetes resource annotations into Prometheus labels without sanitization. For Secrets specifically, the default kubectl behavior of showing decoded secret data in annotations combined with these metric generators led to secret leakage. The kubeAnnotationsToPrometheusLabels function was the common vulnerable component across all resource types.
