CVE-2026-58080

Description

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.
