React version 0.5.0, released on January 18, 2012, represents a minor update to the 0.3.5 version, released just a day earlier on January 17, 2012, of this early JavaScript library designed to simplify asynchronous programming. Both versions share the same core functionality: a lightweight rules engine intended to reduce boilerplate, improve error handling and exception management, and manage variable and task dependencies within asynchronous workflows. This makes it easier for developers to construct complex applications that rely on asynchronous operations.
The dependency structure remains consistent between the two versions, relying on sprintf, ensure-array, and eventemitter2. Similarly, devDependencies for testing and promises, including tap, tapr, Deferred, and promised-io, are the same. This suggests that the core focus wasn't on adding new features, but rather on bug fixes, performance enhancements, or minor internal adjustments.
The similarity of the dependency declarations suggests the API of the library was not changed and there wasn't new functionalities.
Developers should consider that due to the temporal proximinity version 0.5.0 fix some bugs existing in the previous one so it makes it a better choice to be used as library.
All the vulnerabilities related to the version 0.5.0 of the package
Cross-Site Scripting in react
Affected versions of react are vulnerable to Cross-Site Scripting (XSS). The package fails to properly sanitize input used to create keys. This may allow attackers to execute arbitrary JavaScript if a key is generated from user input.
If you are using react 0.5.x, upgrade to version 0.5.2 or later.
If you are using react 0.4.x, upgrade to version 0.4.2 or later.
Cross-Site Scripting in react
Versions of react prior to 0.14.0 are vulnerable to Cross-Site Scripting (XSS). The package's createElement function fails to properly validate its input object, allowing attackers to execute arbitrary JavaScript in a victim's browser.
Upgrade to version 0.14.0 or later.
