| GHSA-xggf-m53x-jc3f | Critical | node-opcua: Namespace-Level RBAC Fail-Open - Anonymous Write/Call Bypass via Unbound `DefaultRolePermissions## Summary An unauthenticated (**Anonymous**) client can **Write** protected Variables and **Call** privileged Methods on any Node that lacks explicit per-node permissions. This follows the inheritance model defined by OPC UA Part 3, §5.2.9, where nodes without an explicit `RolePermissions` attribute inherit the namespace `DefaultRolePermissions`. OPC 10000-3 §4.8.3 mandates a **default-deny** evaluation (`Bad_UserAccessDenied` when the operation bits are not set); `node-opcua` instead **grants all permissions**. The root cause is a combination of an authorization **fail-open** and a **disc |
