No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In Eclipse Milo versions 1.0.0 through 1.1.4, OpcUaServerConfig.copy() fails to preserve a configured RoleMapper. On servers that rely on role permissions and construct the running configuration through copy(), sessions receive no role IDs and the default access controller skips role-permission checks, allowing an anonymous client where anonymous sessions are permitted to read role-permission metadata, invoke protected methods, or delete protected nodes.
