Overview
Affected versions of this package are vulnerable to Reachable Assertion through the createIndex process when certain index types, such as "2dsphere_bucket" on non-timeseries bucket collections or "queryable_encrypted_range" indices, are used. An attacker can cause the server to crash by inserting a document that triggers an update to the affected index.
