CVE-2026-78427
Medium
Description
The NeuVector admission webhook silently excludes containers from policy evaluation when their image path matches one of three hardcoded service mesh sidecar images. Since the image path is entirely controlled by the workload author, any user capable of deploying workloads can evade admission deny rules simply by naming their image path after one of these sidecar images.
