WHY IT NEEDS A POLICY

Why snow_property_bulk needs a policy

This tool performs both read and write operations on system properties, but the explicit mention of 'set' (modification) makes it Write category. The 'bulk' aspect and system-level scope elevate severity to high, as misconfigured or malicious property changes could affect ServiceNow instance behavior, security configurations, or integrations.

From the tool's definition Bulk system property operations (get/set multiple) — the 'set multiple' capability indicates modification of system properties at scale.
