Babel-preset-react-app is a crucial Babel preset tailored for Create React App projects, streamlining the process of transforming modern JavaScript and JSX code into browser-compatible formats. Comparing versions 3.1.1 and 3.1.0, developers will find minimal differences in core dependencies. Both versions rely on the same set of Babel plugins and presets, including babel-preset-env, babel-preset-react, and plugins for handling JSX transformations, dynamic imports, and other modern JavaScript features. This ensures a consistent compilation environment for React applications created with Create React App.
The key distinction lies in release date, with version 3.1.1 released on January 15, 2018, while version 3.1.0 dates back to October 30, 2017. This suggests that version 3.1.1 likely incorporates minor bug fixes, internal improvements, or dependency updates that don't fundamentally alter the preset's functionality. For developers, this means upgrading from 3.1.0 to 3.1.1 should be a straightforward process with minimal risk of introducing breaking changes. Staying up-to-date with the latest version, even with minor updates, is generally recommended to benefit from potential enhancements and security patches. The consistent dependency list signifies a stable and reliable preset for transforming React code, making it a dependable choice for Create React App users. The babel-runtime peer dependency ensures that necessary helper functions are available for the transformed code.
All the vulnerabilities related to the version 3.1.1 of the package
Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code
Using Babel to compile code that was specifically crafted by an attacker can lead to arbitrary code execution during compilation, when using plugins that rely on the path.evaluate()
or path.evaluateTruthy()
internal Babel methods.
Known affected plugins are:
@babel/plugin-transform-runtime
@babel/preset-env
when using its useBuiltIns
option@babel/helper-define-polyfill-provider
, such as babel-plugin-polyfill-corejs3
, babel-plugin-polyfill-corejs2
, babel-plugin-polyfill-es-shims
, babel-plugin-polyfill-regenerator
No other plugins under the @babel/
namespace are impacted, but third-party plugins might be.
Users that only compile trusted code are not impacted.
The vulnerability has been fixed in @babel/traverse@7.23.2
.
Babel 6 does not receive security fixes anymore (see Babel's security policy), hence there is no patch planned for babel-traverse@6
.
@babel/traverse
to v7.23.2 or higher. You can do this by deleting it from your package manager's lockfile and re-installing the dependencies. @babel/core
>=7.23.2 will automatically pull in a non-vulnerable version.@babel/traverse
and are using one of the affected packages mentioned above, upgrade them to their latest version to avoid triggering the vulnerable code path in affected @babel/traverse
