Yargs version 10.1.0 arrives as a modest update following version 10.0.3, bringing subtle refinements to this popular command-line argument parser. While both maintain the same core description and MIT license, several dependency upgrades indicate the shifts under the hood.
One key visible difference lies in the dependencies. Yargs 10.1.0 adopts cliui version 4.0.0, moving up from cliui 3.2.0. More notably, yargs-parser sees an increment from version 8.0.0 to 8.1.0. Developers should investigate these changes, particularly in yargs-parser, as they might influence how arguments are parsed and handled in their applications.
For developers integrating Yargs into their projects, examining the changelogs of cliui and yargs-parser is crucial. These updated dependencies could introduce new features, bug fixes, or even breaking changes affecting existing Yargs implementations. Although the jump from 10.0.3 to 10.1.0 might seem minor, these dependency tweaks could enhance argument parsing capabilities and potentially improve the robustness of command-line interfaces built with Yargs. It's also interesting to notice the release date difference, as there are roughly 3 months between the releases of both versions. Always ensure compatibility with your existing codebase when upgrading and consider thorough testing after upgrading.
All the vulnerabilities related to the version 10.1.0 of the package
Regular Expression Denial of Service (ReDoS) in cross-spawn
Versions of the package cross-spawn before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.
Denial of Service in mem
Versions of mem prior to 4.0.0 are vulnerable to Denial of Service (DoS). The package fails to remove old values from the cache even after a value passes its maxAge property. This may allow attackers to exhaust the system's memory if they are able to abuse the application logging.
Upgrade to version 4.0.0 or later.
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.
