CVE-2026-105112 Details

Description

Nezha from 1.8.0 before 2.3.13 contains a lock-order inversion in UpdateGroup and DeleteGroup that allows authenticated non-admin users to deadlock the alerting subsystem. Attackers can concurrently call the notification-group and batch-delete endpoints with oversized id lists to widen the race and close an ABBA cycle, permanently killing alert delivery until restart.
