CNA source text (English)
Cross-database write retargeting via unvalidated dotted database name in Client.BulkWrite in the MongoDB Go Driver
The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name could therefore have the write directed at a database and collection other than the ones it intended. Only the Client.BulkWrite API is affected.
