Babel-preset-stage-3 is a vital collection of Babel plugins designed to enable cutting-edge JavaScript features that are currently in stage 3 of the TC39 standardization process. Using this preset allows developers to experiment with and leverage proposals nearing official adoption, enhancing their code with modern syntax and capabilities well before they are universally supported in JavaScript engines.
Comparing versions 6.0.15 and 6.1.2, the core functionality and declared dependencies remain consistent: both rely on "babel-plugin-transform-async-to-generator" and "babel-plugin-transform-exponentiation-operator" to handle asynchronous operations and the exponentiation operator, respectively. This means that the set of language features supported by the preset is unchanged between these versions.
The most noticeable difference between the two versions lies in their release dates. Version 6.0.15 was released on November 1st, 2015, while version 6.1.2 followed shortly after, on November 5th, 2015. The exact nature of the changes introduced in version 6.1.2 is not specifically detailed in available data, but the quick release cycle suggests that it may include bug fixes, performance improvements, or minor compatibility adjustments. Developers should consult the changelog or commit history within the linked GitHub repository for detailed information.
For developers seeking to utilize stage 3 features, Babel-preset-stage-3 continues to offer a convenient way to incorporate these features in their projects. By installing the preset, developers can stay ahead of the curve and use these features in new projects.
All the vulnerabilities related to the version 6.1.2 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-regeneratorNo 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 versions:
@babel/plugin-transform-runtime v7.23.2@babel/preset-env v7.23.2@babel/helper-define-polyfill-provider v0.4.3babel-plugin-polyfill-corejs2 v0.4.6babel-plugin-polyfill-corejs3 v0.8.5babel-plugin-polyfill-es-shims v0.10.0babel-plugin-polyfill-regenerator v0.5.3
