Babel plugin transform-es2015-modules-commonjs is a crucial tool for developers using Babel to transpile modern JavaScript (ES2015 and beyond) into code that can be understood by older environments, specifically those relying on the CommonJS module system . Modules enable better code organization and reusability, but older environments may not natively support the import/export syntax. This plugin bridges that gap, ensuring compatibility.
Comparing version 6.1.3 with the older 6.0.18, the core functionality remains consistent: transforming ES2015 module syntax into CommonJS-compatible require and module.exports statements. Both versions share the same dependencies on core Babel packages like babel-types, babel-runtime, babel-template, and babel-plugin-transform-strict-mode, indicating a stable architecture.
The key difference between 6.1.3 and 6.0.18 lies in bug fixes, performance improvements, and minor internal tweaks. The newer version, released just two days after 6.0.18, suggests it addresses immediate issues discovered in the initial release. While the changelog isn't provided in the data, such a quick update cycle usually indicates critical fixes. Developers should always prefer the latest stable version for enhanced reliability. Although the core functionalities are identical, version 6.1.3 offers a more refined and stable experience due to these improvements and fixes.

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:
