However, Flowise&#39;s inherent authentication and authorization model is minimal and lacks role-based access controls (RBAC). Furthermore, in Flowise versions before 3.0.1 the default installation operates without authentication unless explicitly configured. This combination allows unauthenticated network attackers to execute unsandboxed OS commands.</p> <p><strong>Affected:</strong> flowise</p> <p>The Custom MCPs feature is designed to execute OS commands, for instance, using tools like `npx` to spin up local MCP Servers.
