A fix is available — apply it.

Nezha Dashboard versions before 2.3.5 fail to restrict service monitor task types to supported probe types, allowing authenticated users with nezha:service:write scope to submit privileged task types through the service API. Attackers can deliver command execution or Agent configuration tasks to Agents within their authorization scope by exploiting the shared protobuf Task.Type namespace between service monitors and privileged operations.
