Dashboard JWTs are sent in the `nz-jwt` cookie and configured with `SameSite=Lax`, which browsers include on top-level cross-site GET navigations. Because this state-changing GET endpoint has no CSRF token, origin validation, or fetch-metadata guard, an attacker can cause a logged-in Nezha user to trigger one of their existing cron tasks by navigating the victim's browser to the manual-trigger URL.\n\nIf the targeted cron task sends a command to an online agent, the stored command is dispatched to the agent task stream. The attacker cannot create or modify the cron command through this issue alone, but can force execution of a command that the victim already saved and is authorized to run.\n\n### Details\nSource-to-sink chain:\n\n1. The dashboard registers the manual cron trigger as a GET route under the authenticated API group: `auth.GET(\"/cron/:id/manual\", commonHandler(manualTriggerCron))` at `cmd/dashboard/controller/controller.go:131-134`.\n2.
