The MongoDB Entity Framework Core provider does not neutralize special elements when it places a caller-supplied value into a bulk update that is expressed as a databasea result, a value supplied as plain data may be interpreted by the database as expression syntax. A part value through normal application input may causeunintended modification of fields in the records the application is updating, and may cause data already held in those records to be relocated into other fields of the same record.
