fix(server): scope CLIENT LIST/INFO/KILL to caller's namespace#3536
Merged
Conversation
Non-admin (tenant) connections could previously enumerate and terminate connections belonging to other namespaces — including the admin namespace and replication links — via CLIENT LIST and CLIENT KILL. Filter both per-worker iteration and the slave-thread enumeration by the caller's namespace, allowing only admin (default-namespace) callers to see or kill connections outside their own namespace.
