MongoDB version 2.1.6 represents a minor update over its predecessor, 2.1.5, primarily focusing on internal improvements and dependency updates. Both versions serve as a legacy driver emulation layer built upon the mongodb-core library, offering a familiar interface for developers accustomed to older MongoDB driver versions. They share the same core dependencies like es6-promise and readable-stream, ensuring consistent handling of asynchronous operations and stream processing. However, the key distinction lies in the updated mongodb-core dependency; version 2.1.6 upgrades this underlying component to 1.3.1, while 2.1.5 relies on version 1.3.0.
This mongodb-core update likely incorporates bug fixes, performance enhancements, and potentially new features within the core MongoDB interaction layer. Developers upgrading to 2.1.6 should anticipate improved stability and efficiency in their database operations due to these underlying enhancements. The extensive list of devDependencies remains consistent between the two versions, showcasing tools used for testing, development, and benchmarking purposes. These include libraries for code coverage (nyc, coveralls), linting (jsdoc), and performance analysis (betterbenchmarks). Both versions are licensed under Apache-2.0 and maintained by Christian Kvalheim, indicating a commitment to open-source principles and a reliable development team. While the functional differences might not be immediately apparent at the API level, the upgraded mongodb-core in 2.1.6 implies a more robust and optimized foundation for interacting with MongoDB databases.
All the vulnerabilities related to the version 2.1.6 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.
