Yargs-parser is a powerful and widely-used option parser designed to be the backbone of the popular yargs command-line argument processing library. Version 7.0.0 follows closely the previous stable release, version 6.0.1, with a minor version bump indicating potentially new features or minor breaking changes. Both versions share the same core dependencies, relying on "camelcase" version "^4.1.0" for converting strings to camel case. The developer toolchain also remains consistent, using "nyc" for coverage, "chai" for assertions, "mocha" for testing, "standard" for code style, "coveralls" for coverage reporting, and "standard-version" for managing releases. This suggests a focus on maintaining code quality and a stable development workflow.
The key distinction between version 7.0.0 and 6.0.1 lies in the update itself. While the specific changes aren't detailed here, developers should investigate the changelog for yargs-parser 7.0.0 to understand the introduced features, bug fixes, and potential breaking changes. The release date of version 7.0.0 is May 2nd, 2017, while version 6.0.1 was released on May 1st, 2017, indicating a very quick follow-up release. This might imply a hotfix or an immediate enhancement based on feedback from the previous version. Developers should always consult the official documentation and release notes on the yargs-parser GitHub repository to fully grasp the implications of upgrading. Both verions are under the ISC license and the repository is the same.
All the vulnerabilities related to the version 7.0.0 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.
