CVE-2026-78424

EUVD-2026-88224

28.09.2026, 12:17

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.
