Mixin-deep is a utility designed for deeply merging properties from multiple objects into a single target object, offering a behavior similar to merge-deep but without the cloning operation, making it potentially faster in scenarios where cloning is unnecessary. Comparing versions 1.0.0 and 1.0.1, the core functionality remains consistent; both versions share the same description, dependencies (for-own and is-plain-object), development dependencies (mocha and should), license (MIT), repository details, and author information. The key difference lies within the release date and the specific tarball URL, indicating that version 1.0.1 is a patch update, presumably addressing minor bug fixes or internal improvements.
For developers, mixin-deep provides a straightforward solution for complex object merging, especially useful in configuration management, data aggregation, and object extension scenarios. The reliance on for-own ensures efficient iteration over object properties, while is-plain-object provides a check to avoid merging non-plain objects. While the difference between versions 1.0.0 and 1.0.1 appears minimal, it's always advisable to use the latest stable version (1.0.1 in this case) to benefit from potential bug fixes or performance enhancements. Developers already using 1.0.0 can consider updating to 1.0.1 with minimal risk, as the API and core functionality remain unchanged. This library can be used when needing to merge configurations where complex configurations such as nested objects are present.
All the vulnerabilities related to the version 1.0.1 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.
