Short explanation
A flaw in the MongoDB C# Driver can cause data designated for client-side field-level encryption to be written without encryption.
This vulnerability defeats the confidentiality guarantee of client-side encryption by persisting sensitive fields in plaintext.
What should be done?
- Follow vendor advisories
- Update affected versions
- Review text-encoding configurations

Show the technical text from the sources
A flaw in the client-side encryption support of the MongoDB .NET/C# driver can cause data designated for client-side field-level encryption to be written without encryption. Under certain platform text-encoding configurations, an internal name conversion loses information, so the encryption layer fails to associate the operation with its configured encryption rules and the operation proceeds without an error being raised. An application user with the ability to write data through an affected application can therefore have sensitive fields persisted in plaintext, defeating the confidentiality guarantee that client-side encryption is intended to provide. No integrity or availability impact was observed.
