Babel plugin transform ES2015 modules commonjs is a crucial tool for developers using Babel to transpile modern JavaScript (ES2015+) into a format compatible with older JavaScript environments that rely on the CommonJS module system. Comparing versions 6.5.0 and 6.5.2 reveals subtle but important updates, primarily affecting dependency management.
The key difference lies in the dependencies section. Version 6.5.2 upgrades the babel-types dependency to "^6.5.2" and babel-plugin-transform-strict-mode to "^6.5.2", whereas version 6.5.0 uses "^6.4.5" and "^6.3.13" respectively for those dependencies. These upgrades signal improvements and potentially bug fixes within the Babel ecosystem itself, ensuring greater compatibility and stability when working with the latest features and syntax transformations. Both versions share common dependencies like babel-runtime and babel-template, which are essential for the plugin's core functionality.
For developers, this means that upgrading to 6.5.2 is generally advisable to leverage these dependency updates and benefit from any associated enhancements. While both versions serve the same core purpose of transforming ES2015 modules to CommonJS, staying current with minor version bumps like this helps to minimize potential compatibility issues and ensures access to the most recent refinements within the Babel toolchain. Always check the Babel changelog for specific details regarding these updates.

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
