Name of the Vulnerable Software and Affected Versions MongoDB Go Driver (affected versions not specified)
Description The client-level bulk write operation in the MongoDB Go Driver fails to escape reserved separator characters in caller-supplied database names before building the target namespace. This allows an application passing untrusted input as a database name to have write operations retargeted to a database and collection other than the intended ones. This issue specifically affects the Client.BulkWrite API.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
