CVE-2026-78424
OS Command Injection in Packet-Capture (Sniffer) Filter leading to Remote Code Execution on Kubernetes Nodes
Improper parameter handling in NeuVector allows any authenticated user who holds the namespaced Runtime Policies (write) permission or anyone with access to NeuVector’s internal gRPC certificate key pair the ability to inject OS commands in the privileged enforcer container, which can lead to the complete compromise of the worker node. This affects NeuVector 5.4 before 5.4.11, NeuVector 5.5 before 5.5.4, NeuVector 5.6 before 5.6.2 and potentially older versions.
