CVE-2019-19729: Improper Input Validation

December 11, 2019 (updated December 19, 2019)

An issue was discovered in the BSON ObjectID (aka bson-objectid). ObjectID() allows an attacker to generate a malformed objectid by inserting an additional property to the user-input, because bson-objectid will return early if it detects _bsontype==ObjectID in the user-input object. As a result, objects in arbitrary forms can bypass formatting if they have a valid bsontype.
