CVE-2026-47120Public exploitNetwork attack vector

Cross-tenant cron execution via unchecked trigger IDs

Published Jun 12, 2026 · Updated Jun 12, 2026

Missing authorization in Nezha Monitoring 1.4.0 through 2.0.7 allows remote authenticated users to trigger other users' cron tasks. The alert-rule and service create or update handlers accept FailTriggerTasks and RecoverTriggerTasks IDs but validate server maps rather than task ownership. RoleMember access and a pre-existing victim cron are required; when the selected alert or monitor trips, SendTriggerTasks executes the stored command on its configured servers.
