Babel plugin transform async to generator, version 6.5.0, refines the process of converting async functions into ES2015 generators, building upon the foundation laid by version 6.4.6. Both versions share the core functionality of enabling developers to use async/await syntax in their code, which is then transformed into compatible ES2015 generator functions, ensuring broader compatibility across different JavaScript environments. Key dependencies like babel-helper-remap-async-to-generator, babel-plugin-syntax-async-functions, and babel-runtime remain consistent, indicating a stable core architecture.
The primary distinction lies in potential bug fixes, performance enhancements, or subtle refinements introduced in version 6.5.0. While the provided data doesn't explicitly detail these internal improvements, the update suggests an ongoing effort to optimize the transformation process. Developers benefit from using either version to leverage the conciseness and readability of async/await while maintaining compatibility with older browsers or JavaScript engines. Upgrading to 6.5.0 is generally recommended to take advantage of any improvements and bug 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:
@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
