CVE-2026-101085: Nezhahq Nezha

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

Nezha before 2.3.8 fails to validate alert rule type and duration bounds, allowing authenticated non-administrator users to create malformed rules that trigger unrecovered panics in the alert evaluator goroutine. Attackers can submit a crafted alert rule via the POST /api/v1/alert-rule endpoint to crash the dashboard process, which persists the rule and causes repeated crashes on restart, disabling all monitoring and control plane functionality.

Affected products

• Nezhahq Nezha: before 2.3.8 (fixed in 2.3.8)
