Yargs-parser is a widely adopted npm package known as the "mighty option parser" favored by the popular yargs command-line argument parser. Comparing versions 4.2.1 and 4.2.0 reveals subtle but potentially impactful changes for developers. Both versions share core functionality, leveraging camelcase for argument parsing. However, the key difference lies in the development dependencies. Version 4.2.1 upgrades standard-version from 3.0.0 to ^4.0.0. This update to standard-version impacts the automation of versioning and changelog generation during the package release process, and although this is not a code-related change, it ensures better and more automated releases.
Crucially, for developers using yargs-parser for their own projects, the core parsing capabilities remain consistent between the two versions. Consider adopting the latest version (4.2.1) mostly to benefit from the newer tooling used in development. For upgrading from older versions of yargs-parser, thoroughly examine the changelog and test your command-line interfaces to ensure seamless transition and compatibility, especially when dealing with specific option configurations or argument parsing rules. Yargs-parser's ease of use and robust feature set makes it a valuable tool for simplifying command-line argument handling in Node.js applications.
All the vulnerabilities related to the version 4.2.1 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.
