About this tag
The kubernetes security tag on WindowsForum.com covers vulnerabilities and hardening guidance for Kubernetes clusters, with a strong emphasis on Azure Kubernetes Service (AKS) and related Microsoft ecosystems. Recent discussions include critical CVEs such as CVE-2026-32193 (AKS remote code execution), CVE-2026-32241 (Flannel command injection leading to root RCE), CVE-2026-26135 (Azure Custom Locations privilege escalation), CVE-2026-26018 (CoreDNS denial-of-service), CVE-2025-13281 (SSRF in Portworx), CVE-2024-7598 (NetworkPolicy bypass during namespace deletion), and multiple KubeVirt flaws (CVE-2025-64436, CVE-2025-64433) affecting VM workload security. Topics span network policy, admission control, identity, storage, and cluster compromise scenarios, providing actionable patch guidance and security best practices for operators.
