Kubernetes — Vulnerabilities & Security Advisories 104

Browse all 104 CVE security advisories affecting Kubernetes. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Kubernetes serves as an open-source container orchestration platform, automating the deployment, scaling, and management of containerized applications across distributed clusters. Its complex architecture, involving numerous interacting components like the API server and kubelet, historically exposes it to diverse vulnerability classes. Common issues include remote code execution (RCE) via unauthenticated API endpoints, privilege escalation through misconfigured role-based access controls, and cross-site scripting (XSS) in the web dashboard. With over 100 recorded CVEs, the platform has faced significant security challenges, including incidents where attackers exploited weak authentication mechanisms to gain cluster-wide control. These vulnerabilities often stem from default configurations or delayed patching of underlying dependencies. Consequently, securing Kubernetes requires rigorous network segmentation, strict identity management, and continuous monitoring to mitigate risks associated with its intricate service mesh and dynamic workload scheduling capabilities.
