Version 2.0.53 of the mongodb npm package is a patch release focusing on stability and improvements built upon the foundation of version 2.0.52. Both versions serve as a legacy driver emulation layer built on top of mongodb-core, providing a familiar interface for developers accustomed to older MongoDB driver versions. The core functionality remains consistent, allowing for seamless interaction with MongoDB databases.
The key difference lies in the underlying mongodb-core dependency. Version 2.0.53 updates this dependency to version 1.2.30, while 2.0.52 used version 1.2.28. This updated mongodb-core likely includes bug fixes, performance enhancements, and potentially new features within the core driver layer that trickle up to the mongodb package. Developers should check the mongodb-core changelog for specific details on those improvements.
Other dependencies like es6-promise and readable-stream remain the same, ensuring consistent behavior for asynchronous operations and stream handling. Similarly, the development dependencies, essential for testing and building the package, are unchanged. This ensures that existing development workflows are not disrupted.
For developers upgrading from 2.0.52, the primary benefit comes from the potential stability and performance gains offered by the updated mongodb-core. While the API remains consistent, the underlying improvements can lead to a more robust and efficient interaction with MongoDB deployments. Reviewing the mongodb-core changes associated with the update is advisable to fully leverage any new capabilities or optimizations. Consider this a minor but important update, potentially resolving underlying issues present in the older driver core.
All the vulnerabilities related to the version 2.0.53 of the package
Denial of Service in mongodb
Versions of mongodb prior to 3.1.13 are vulnerable to Denial of Service. The package fails to properly catch an exception when a collection name is invalid and the DB does not exist, crashing the application.
Upgrade to version 3.1.13 or later.
Deserialization of Untrusted Data in bson
Incorrect parsing of certain JSON input may result in js-bson not correctly serializing BSON. This may cause unexpected application behaviour including data disclosure.
Deserialization of Untrusted Data in bson
All versions of bson before 1.1.4 are vulnerable to Deserialization of Untrusted Data. The package will ignore an unknown value for an object's _bsontype, leading to cases where an object is serialized as a document rather than the intended BSON type.
