CVE-2026-86831: Improper validation of pod identifier uniqueness in aws-network-policy-agent in Amazon EKS
Bulletin ID: 2026-113-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/16/2026 12:30 PM PDT Description: Network Policy Agent is an EKS Policy management feature. We identified CVE-2026-86831, a cross-namespace NetworkPolicy bypass in Amazon EKS Network Policy Agent (aws-network-policy-agent) before v1.4.0. Pod identifiers are constructed by concatenating the pod name and namespace with a hyphen delimiter, which is a legal character in both Kubernetes pod names and namespace names. This ambiguity can produce identical identifiers for pods across different namespaces, potentially allowing NetworkPolicy enforcement to be bypassed. Impacted versions: - 1.14.0<1.22.3 Amazon VPC CNI Managed Add-on - < v1.4.0 Network Policy Agent Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
