Yargs is a popular npm package that helps developers build interactive command-line tools with ease. Versions 9.0.0 and 9.0.1 are quite similar, sharing the same core dependencies like y18n, cliui, camelcase, and yargs-parser, ensuring consistent handling of internationalization, command-line interface styling, string casing, and argument parsing. The development dependencies also remain identical, suggesting a focus on maintaining the existing development workflow and testing infrastructure.
The key difference between these versions lies in their release dates. Version 9.0.0 was released on September 3rd, 2017, while version 9.0.1 followed shortly after on September 17th, 2017. This relatively quick release cycle often indicates that version 9.0.1 includes bug fixes, minor improvements, or security patches that address issues discovered in version 9.0.0. While the specific changes aren't detailed in the provided data, developers upgrading from 9.0.0 to 9.0.1 can expect a more stable and reliable experience. For those starting a new project, it's always recommended to use the latest stable version (9.0.1 in this case) to benefit from the most up-to-date fixes and enhancements. Developers can leverage yargs to streamline command-line argument parsing, create intuitive help messages, and build robust command-line applications, improving user experience and developer productivity.
All the vulnerabilities related to the version 9.0.1 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.
