The GitHub commit 2dad811 explicitly adds a @security.private decorator to enumerateRoles in ZODBRoleManager.py. This indicates the method was previously missing access controls, allowing unauthenticated role enumeration. The CVE description confirms this as an information disclosure vulnerability in ZODBRoleManager's role listing functionality.
