Summary
Nezha 1.8.0 before 2.3.13 Denial of Service via Notification Mutex Deadlock
Details

Nezha Dashboard from 1.8.0 before 2.3.13 contains an improper locking vulnerability where a non-deferred mutex unlock leaks on a nil-map panic path. Any authenticated non-admin member can issue four notification API calls to permanently deadlock the alerting subsystem, then exhaust memory with blocking requests.
