CVE-2026-89203
A vulnerability has been identified in RUGGEDCOM CROSSBOW (All versions < V6.0). Affected devices do not properly restrict access to various database queries, allowing users to retrieve system-wide information that is not intended for their privilege level. This could allow an authenticated attacker to gather sensitive information about the system's infrastructure, including details on all devices, substations, users, and scheduled activities.
