CVE-2026-114654 BSON output corruption via out-of-range binary subtype bypassing UUID and OldBinary guards

A numeric-type conversion flaw in the BSON handling library of the MongoDB C Driver allows an out-of-range binary subtype value supplied through untrusted textual input to bypass the library's binary-element integrity checks. When such a value is later encoded, it is narrowed to a smaller wire...

CVE-2026-114654

The MongoDB C# Driver contains a numeric-type conversion flaw in its BSON handling library . An unauthenticated party can provide untrusted textual input containing an out-of-range binary subtype value , which bypasses integrity checks. During subsequent encoding, the value is narrowed to a small...

CVE-2026-114646 NoSQL command injection via mismatched raw BSON length prefix written verbatim to the wire

A data-validation flaw exists in the BSON handling and binary serialization path of the MongoDB C Driver. When an application constructs a raw or lazy BSON document object from externally supplied binary data, the driver does not verify that the size quantity declared inside that data matches the...

CVE-2026-114646

A data-validation flaw in the MongoDB C# Driver affects the BSON handling and binary serialization path. When an application constructs a raw or lazy BSON document from externally supplied binary data, the driver fails to verify if the declared size quantity matches the actual data provided. This...
