CVE-2026-81521: Mongodb Bulkwrite Unvalidated Database Namespacecve-2026-81521-mongodb-bulkwrite-unvalidated-database-namespace

Bulk write operations on ClientBulkWrite structs do not validate that database names are free of '.' characters. MongoDB server splits namespaces on the first period, so unvalidated database names containing '.' can retarget writes to unintended databases and collections.
