Cross-env is a valuable tool for JavaScript developers, streamlining cross-platform environment variable management within npm scripts. Comparing versions 5.0.0 and 4.0.0, a subtle evolution is apparent. Both versions maintain identical core functionalities, indicated by the consistent dependencies on "is-windows" and "cross-spawn." These dependencies underpin the core function of reliably setting and utilizing environment variables across diverse operating systems, eliminating the need for platform-specific conditional scripting.
The "devDependencies" also remain the same, suggesting no alterations to the development workflow or testing environment between these releases. These include widely used tools like ESLint for code linting, Jest for testing, and Babel for transpilation, alongside utilities for managing contributions, commit messages, and semantic releases.
Given the stability in both "dependencies" and "devDependencies," the primary reason to upgrade to version 5.0.0 likely involves minor bug fixes, performance enhancements, and potential adjustments to internal tooling, which aren't explicitly detailed in the provided metadata. While the functional changes aren't drastically apparent from this data, developers should consider upgrading to the latest minor version to benefit from the most up-to-date improvements and ensure compatibility with newer Node.js versions and related tooling. Always refer to the changelog for the most precise details on specific modifications and potential breaking changes.
All the vulnerabilities related to the version 5.0.0 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.
