Kubernetes — Vulnerabilities & Security Advisories 52

All 52 CVE vulnerabilities found in Kubernetes, with AI-generated Chinese analysis, references, and POCs.

This page aggregates known security vulnerabilities, weakness types, and associated tags for the Kubernetes product from the CNCF vendor. It collects data on misconfigurations, privilege escalation flaws, denial of service risks, and other critical defects affecting the container orchestration platform. The repository covers vulnerability reports spanning from the initial public releases up to the present day, ensuring a comprehensive historical view of security incidents. Visitors can use this resource to track vendor advisories issued by the Kubernetes Security Team, understand the prevalence and impact of specific weakness classes across different cluster versions, and look up the product's complete vulnerability history to assess long-term exposure trends. By consolidating disparate sources into a single view, this aggregation helps security professionals and operations teams monitor patch requirements and prioritize remediation efforts based on severity and exploitability. The data includes information on component-level flaws, API server vulnerabilities, and control plane weaknesses that may impact cluster integrity. This structured approach facilitates deeper analysis of security postures without requiring manual cross-referencing of multiple bulletin boards or mailing list archives. Users can filter entries by severity rating, publication date, or specific Kubernetes modules to find relevant context for their environment. This centralized catalog serves as a reference for compliance audits and risk assessments, providing clear visibility into the security landscape surrounding one of the most widely used container management systems in modern infrastructure deployments.
