MongoDB Node.js driver version 2.1.8 represents a minor update over its predecessor, 2.1.7, focusing on core improvements and potentially bug fixes. Both versions maintain the same core set of dependencies crucial for operation, including es6-promise, mongodb-core, and readable-stream, ensuring continued compatibility and functionality related to asynchronous operations, core MongoDB interaction, and stream handling respectively.
The primary difference lies within the specific version of mongodb-core, upgraded from 1.3.1 in 2.1.7 to 1.3.5 in 2.1.8. This bump in the core driver likely encompasses internal enhancements, performance tweaks, and resolutions to identified issues, contributing to a more stable and efficient interaction with MongoDB databases. While the developer-facing API remains consistent, this update can lead to tangible improvements in application performance and reliability.
Both versions share an extensive list of development dependencies, showcasing a commitment to rigorous testing and development practices. Tools like nyc for code coverage, jsdoc for documentation generation, and integra for integration testing highlight the project's dedication to quality. Notably, betterbenchmarks suggests a focus on performance evaluation. For developers, this translates to a reliable and well-tested driver, providing confidence in its stability and adherence to best practices. Upgrading from 2.1.7 to 2.1.8 should generally be seamless, with the primary benefit being the enhanced mongodb-core component.
All the vulnerabilities related to the version 2.1.8 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.
