React-dev-utils is a collection of helpful utilities primarily designed for projects bootstrapped with Create React App, streamlining the development workflow when using Webpack. Version 0.4.1 represents a minor patch release following version 0.4.0, both intended to enhance the development experience. Examining the metadata, the key difference lies primarily in the release date, with version 0.4.1 being released on December 7, 2016, a few days after version 0.4.0 on December 3, 2016. The dependencies listed—including opn, chalk, ansi-html, strip-ansi, html-entities, sockjs-client, and escape-string-regexp—remain identical between the two versions, suggesting that the core functionality and external libraries utilized haven't changed.
This update from 0.4.0 to 0.4.1 likely involves minor bug fixes, performance tweaks, or internal improvements that don't necessitate bumping the minor version. For developers utilizing react-dev-utils, this suggests a stable and reliable library that receives regular maintenance. While the specific code modifications aren't detailed in the provided data, upgrading to version 0.4.1 is recommended to benefit from the latest refinements and ensure compatibility with the broader Create React App ecosystem. Developers can easily pull the update from the npm registry using standard package management commands to maintain an optimized and up-to-date development environment.
All the vulnerabilities related to the version 0.4.1 of the package
react-dev-utils OS Command Injection in function getProcessForPort
react-dev-utils prior to v11.0.4 exposes a function, getProcessForPort, where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.
Uncontrolled Resource Consumption in ansi-html
This affects all versions of package ansi-html. If an attacker provides a malicious string, it will get stuck processing the input for an extremely long time.
Exposure of Sensitive Information in eventsource
When fetching an url with a link to an external site (Redirect), the users Cookies & Autorisation headers are leaked to the third party application. According to the same-origin-policy, the header should be "sanitized."
