Babel preset stage-3 offers a convenient way to enable ECMAScript stage 3 features in your JavaScript projects, allowing you to use cutting-edge syntax with confidence. Comparing version 6.22.0 with the older 6.17.0 reveals key updates in its underlying dependencies.
Specifically, version 6.22.0 upgrades several core plugins to their ^6.22.0 counterparts, including: babel-plugin-syntax-trailing-function-commas, babel-plugin-transform-async-generator-functions, babel-plugin-transform-async-to-generator, babel-plugin-transform-exponentiation-operator, and babel-plugin-transform-object-rest-spread. This coordinated update ensures compatibility and potentially incorporates bug fixes, performance improvements or new functionalities within those individual plugins.
In contrast, version 6.17.0 relies on older versions of these plugins, like babel-plugin-transform-async-to-generator at ^6.16.0 and babel-plugin-syntax-trailing-function-commas at ^6.3.13. Developers upgrading to 6.22.0 benefit from the unified versioning across these plugins, streamlining dependency management and reducing the risk of version conflicts. By keeping babel-preset-stage-3 and its dependencies up to date, developers gain access to the latest features and improvements related to stage 3 proposals being implemented by Babel. Using the latest version can also improve the efficiency of the transpilation process and allow the use of advanced Javascript features.

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
