Mixin-deep is a utility for deeply merging properties from multiple objects into a single target object, similar to merge-deep but without cloning. This makes it a performant choice if you're working with large objects and want to avoid the overhead of creating copies. Comparing version 1.1.1 with the immediately preceding 1.1.0, reveals subtle but important refinements.
One key difference lies in how its dependencies are managed. In version 1.1.0, is-plain-object dependency was specified by its direct tarball URL which is usually less reliable and less manageable than just referring it by version. In v1.1.1, this changes to a standard version specifier ^2.0.0, enhancing maintainability and potentially allowing for automatic security updates. The license information is also represented differently; in 1.1.0 it's an object with type and URL while in 1.1.1 it is simplified to a plain string "MIT". Another change is in the repository URL, 1.1.0 contained git://, while 1.1.1 uses https://. Finally, the releaseDate signifies a roughly one-month gap between the two versions, suggesting bug fixes or minor enhancements were implemented during this period.
For developers, mixin-deep offers a simple yet powerful tool for managing object properties. The absence of cloning can significantly boost performance, particularly when dealing with nested or large objects. When choosing the apropriate version, prefer the newest to avoid potential known problems that might be present in past versions of the package.
All the vulnerabilities related to the version 1.1.1 of the package
Prototype Pollution in mixin-deep
Versions of mixin-deep
before 1.3.1 are vulnerable to prototype pollution via merging functions.
Update to version 1.3.1 or later.
Prototype Pollution in mixin-deep
Versions of mixin-deep
prior to 2.0.1 or 1.3.2 are vulnerable to Prototype Pollution. The mixinDeep
function fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.
If you are using mixin-deep
2.x, upgrade to version 2.0.1 or later.
If you are using mixin-deep
1.x, upgrade to version 1.3.2 or later.
