Yargs version 4.3.0 is a minor update to the popular command-line argument parsing library, building upon the foundation laid by version 4.2.0. Both versions share the same core dependencies, including y18n for internationalization, cliui for building command-line interfaces, pkg-conf for package configuration, and yargs-parser for parsing arguments. This ensures continued stability and feature parity for developers relying on these underlying components. The development dependencies also remain consistent, indicating a focus on maintaining the existing testing and code quality infrastructure.
The most notable change in version 4.3.0 is its slightly later release date, suggesting that the update primarily contains bug fixes, performance improvements, or minor enhancements rather than significant new features. Developers migrating from version 4.2.0 can likely expect a seamless transition with minimal code adjustments, while benefiting from increased stability or subtle improvements in argument parsing behavior.
For developers choosing between the two versions, opting for yargs 4.3.0 is generally recommended, as it represents the most recent iteration with potential refinements and bug fixes. Both version 4.2.0 and 4.3.0 of Yargs remain excellent choices for developers seeking a lightweight and versatile solution for parsing command-line arguments in their Node.js applications.
All the vulnerabilities related to the version 4.3.0 of the package
yargs-parser Vulnerable to Prototype Pollution
Affected versions of yargs-parser are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --foo.__proto__.bar baz' adds a bar property with value baz to all objects. This is only exploitable if attackers have control over the arguments being passed to yargs-parser.
Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.
