AI agents call pfsense_list_routing_gateway_group_priorities to retrieve information from Pfsense without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' verb indicates this is a Read operation that retrieves existing routing gateway group priority data without modification. However, severity is elevated to 'medium' rather than 'low' because the pfSense context involves critical network infrastructure—an attacker gaining knowledge of gateway group priorities could inform network topology attacks or failover strategy exploitation, even though the tool…
