About Kubernetes 1.23
Kubernetes 1.23 reached end of life on February 28, 2023, roughly 3 years ago. Since then, no security patches have been issued. If you are still running Kubernetes 1.23, you should treat upgrading as a high-priority item. Any CVEs discovered against this version will not be fixed upstream.
The recommended upgrade target is Kubernetes 1.35. You are 3 major versions behind, so review the changelog for each version in between to catch any breaking changes. A staged upgrade through each major version is often safer than jumping directly.
