9.8 criticalEPSS 1.3%

Critical (9.8) in apache hertzbeat. EPSS 1.3% chance of exploitation in the next 30 days.

Hertzbeat is a real-time monitoring system. In `CalculateAlarm.java`, `AviatorEvaluator` is used to directly execute the expression function, and no security policy is configured, resulting in AviatorScript (which can execute any static method by default) script injection. Version 1.4.1 fixes this vulnerability.
