Yargs is a lightweight and versatile command-line argument parser for Node.js, designed to simplify the process of building interactive command-line tools. Comparing versions 1.0.11 and 1.0.12 reveals minimal changes but highlights the project's active maintenance. Crucially, both versions share the same core dependencies, relying on minimist for argument parsing and utilizing tap and hashish for development-related tasks like testing. The consistent license, MIT/X11, ensures broad compatibility and permissive usage. Developers familiar with either version will find a seamless experience transitioning between the two.
Fundamentally, Yargs provides a straightforward way to define and parse command-line options, simplifying how your application interacts with user inputs. The library excels at turning command-line arguments into a usable JavaScript object, streamlining your development workflow of creating command-line interfaces (CLIs). Although the functional differences between 1.0.11 and 1.0.12 are subtle, the successive releases, separated by a short time, signifies commitment to stability and demonstrates continuous improvements. The active development, hosted on GitHub, suggests an evolving package that is actively supported. Developers focusing on long-term stability and low-impact updates can feel confident integrating it into projects where command-line argument parsing is essential.
All the vulnerabilities related to the version 1.0.12 of the package
Prototype Pollution in minimist
Affected versions of minimist 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 --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
