CVE-2026-81530

MongoDB C# Driver has a weakness in its client-side encryption configuration where KMS key-management credentials supplied by the application are serialized verbatim into the driver's human-readable diagnostic settings representation instead of being masked like other secret fields. An attacker w...

CVE-2026-81530 KMS master key exposure via unredacted credential serialization in driver settings string

A weakness in the client-side encryption configuration surface of the MongoDB C Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked...
