Lodash.mergewith offers a modular approach to leveraging the _.mergeWith functionality of the popular Lodash library, allowing developers to selectively import and utilize this specific method without incorporating the entire Lodash suite. Both versions 4.6.0 and 4.5.1 provide the same core functionality: deeply merging objects with a customizer. The primary distinction lies in the release date and potentially subtle internal improvements or bug fixes incorporated in the newer version. Version 4.6.0 was released on August 13, 2016, while version 4.5.1 came out on July 31, 2016.
For developers deciding between these two versions, upgrading to 4.6.0 is generally advisable to benefit from the latest refinements. While the core API remains consistent, newer versions often include performance enhancements, minor bug resolutions, and compatibility adjustments that contribute to a more robust and reliable experience. Lodash.mergewith is particularly useful when you need fine-grained control over how objects are merged. The customizer function allows you to tailor the merging process, resolve conflicts, or apply specific transformations to values during the merge. This granular control is invaluable for complex data structures and scenarios where a simple object merge would be insufficient. Ultimately, lodash.mergewith simplifies complex data manipulation, promotes code clarity, and streamlines development using only the _.mergeWith method.
All the vulnerabilities related to the version 4.6.0 of the package
Prototype Pollution in lodash.mergewith
Versions of lodash.mergewith before 4.6.1 are vulnerable to Prototype Pollution. The function 'mergeWith' may allow a malicious user to modify the prototype of Object via __proto__ causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.6.1 or later.
Prototype Pollution in lodash.mergewith
Versions of lodash.mergewith before 4.6.2 are vulnerable to prototype pollution. The function mergeWith may allow a malicious user to modify the prototype of Object via {constructor: {prototype: {...}}} causing the addition or modification of an existing property that will exist on all objects.
Update to version 4.6.2 or later.
