coredns — Vulnerabilities & Security Advisories 10

CoreDNS serves as a flexible DNS server and proxy, widely used in Kubernetes environments for service discovery and DNS resolution. Historically, vulnerabilities have included remote code execution, cross-site scripting, and privilege escalation, often stemming from improper input validation and insecure default configurations. While no major public incidents have been widely documented, the 10 recorded CVEs highlight potential risks in plugin handling and memory management. Security characteristics include a modular plugin architecture that can introduce attack surfaces, though regular updates and proper configuration mitigate many threats. The project maintains a responsive security team, but administrators should remain vigilant about plugin dependencies and access controls to prevent exploitation.
