Technical Description
Babel is a compiler for writingJavaScript. In `@babel/traverse` prior to versions 7.23.2 and 8.0.0-alpha.4 and all versions of `babel-traverse`, 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; and any "polyfill provider" plugin that depends on `@babel/helper-define-polyfill-provider`, such as `babel-plugin-polyfill-corejs3`, `babel-plugin-polyfill-corejs2`, `babel-plugin-polyfill-es-shims`, `babel-plugin-polyfill-regenerator`. No 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/[email protected]` and `@babel/[email protected]`. Those who cannot
Remediation
Check the references section for vendor advisories and patches from debian. Update debian_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
