Nezha 2.0.0 before 2.4.0 Startup NULL Pointer Dereference via Orphaned Service History

Impact

Nezha 2.0.0 before 2.4.0 contains a NULL pointer dereference vulnerability in ServiceSentinel.loadTodayStats that allows authenticated users to crash the dashboard by deleting a service. Attackers can delete their own service via POST /api/v1/batch-delete/service, leaving orphaned service_histories rows that crash the non-TSDB dashboard on its next startup until removed manually.
