CVE-2026-78427Admission Control Bypass via Hardcoded Sidecar Image Exemption
Medium 5.3
In plain English
A medium-severity security flaw in github.com/neuvector/neuvector from SUSE. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 14% of all known vulnerabilities).
Official 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.
