Lodash.merge is a popular JavaScript utility function for deeply merging objects, and versions 4.3.5 and 4.3.4 represent incremental improvements in this functionality. Both versions share the same core dependencies critical for its operation: lodash.\_baseclone for deep cloning, lodash.\_stack for managing recursion, lodash.isplainobject for identifying plain objects, lodash.keysin for iterating over object keys, and lodash.rest for handling rest parameters. This consistent dependency structure ensures a stable and predictable merging process across both versions.
The primary difference between these versions lies in their release dates and likely subtle bug fixes or performance enhancements. Version 4.3.4 was released on April 3rd, 2016, while version 4.3.5 followed shortly after on April 13th, 2016. This quick succession suggests that 4.3.5 addresses issues discovered in 4.3.4, making it the preferable choice for developers seeking the most stable and up-to-date merging capabilities.
For developers, lodash.merge simplifies complex object manipulation, allowing for easy combination of data from multiple sources into a single object. By using lodash.merge, you can avoid manually iterating and assigning properties, which is error-prone and time-consuming. Lodash.merge handles nested objects and arrays gracefully with overwriting or recursively merging values, offering efficiency and correctness across JavaScript projects.
All the vulnerabilities related to the version 4.3.5 of the package
Prototype Pollution in lodash.merge
Versions of lodash.merge
before 4.6.1 are vulnerable to Prototype Pollution. The function 'merge' 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.merge
Versions of lodash.merge
before 4.6.2 are vulnerable to prototype pollution. The function merge
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.
