RISK

Why gcp_vpc_delete_firewall is rated Critical

Deleting a firewall rule is an irreversible action that removes security controls from a VPC. This can immediately expose cloud infrastructure to unauthorized network access, compromise security posture, and disrupt legitimate traffic flows. The blast radius is critical because firewall rules are foundational security boundaries in cloud infrastructure.

From the tool's definition Tool name contains 'delete' and description states 'Delete a firewall rule'. Firewall rules are security controls that cannot be restored without explicit recreation.
