Yargs-parser is a powerful and widely used option parsing library underpinning the popular yargs command-line argument parser. Version 8.1.0 builds upon the stable foundation of 8.0.0, offering subtle but potentially impactful enhancements for developers relying on robust command-line argument handling.
A primary difference lies in the updated development dependencies. Version 8.1.0 sees the introduction of standard-version at version 4.3.0-candidate.0, whereas 8.0.0 uses standard-version at version 4.0.0. The nyc package, a coverage reporter, is also updated from version 11.2.1 to 11.4.1. These changes suggest improvements in the release process and code coverage testing, potentially leading to more reliable and well-tested code. Developers might find that contributing to 8.1.0 benefits from a more streamlined release workflow, or even better test coverage reports.
The core functionality and primary dependency, camelcase, remain consistent, indicating that the fundamental argument parsing behavior is unchanged. This assures users that upgrading to 8.1.0 shouldn't introduce breaking changes in their existing yargs-parser integrations. The library continues to be released under the ISC license, upholding its permissive usage terms. The focus appears to be on the refinement and maintenance of the existing codebase and processes, offering developers a stable and dependable argument parsing solution. The updated release date also indicates recent activity, making it a more attractive and current choice.
All the vulnerabilities related to the version 8.1.0 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.
