Yargs, a lightweight option parsing library for Node.js, provides a simple way to handle command-line arguments in your applications. Comparing versions 1.2.5 and 1.2.6 reveals a minor update likely focused on bug fixes or minor enhancements, given the small version increment. Both versions share identical core features: parsing command-line arguments into an argv hash without requiring predefined option strings. This offers flexibility and ease of use.
Developers will find both versions useful for streamlining command-line input processing. The consistent dependencies, using minimist for argument parsing, chai, mocha, and hashish for testing, suggest a stable and well-tested foundation. The MIT/X11 license ensures permissive usage in various projects.
Alex Ford of CodeTunnel.com authors both versions, indicating continuity in development and maintenance. The critical distinction lies in the release dates and potentially subtle internal improvements. Version 1.2.6 was released on June 23, 2014, a few days after version 1.2.5, released June 18, 2014. Choose the latest version (1.2.6) for potentially improved stability and resolved issues. Yargs offers a developer-friendly method for managing command-line input.
All the vulnerabilities related to the version 1.2.6 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).
