Security Impact
CVSS: 9.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
How to Fix CVE-2023-45133
To remediate this vulnerability, upgrade all affected @babel/traverse dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @babel/traverse@7.23.2
npm install @babel/traverse@8.0.0-alpha.4
npm install babel-traverse@Latest secure release
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @babel/traverse
How to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2023-45133, inspect your project dependencies using npm:
npm ls @babel/traverse
Analyze the terminal output to locate any version of @babel/traverse in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.23.2), your application is affected.
Note: The npm ls @babel/traverse command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-184: Incomplete List of Disallowed Inputs, where the product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete. In @babel/traverse, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nUsing 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.\n\nKnown affected plugins are:\n- `@babel/plugin-transform-runtime`\n- `@babel/preset-env` when using its [`useBuiltIns`](https://babeljs.io/docs/babel-preset-env#usebuiltins) option\n- 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`\n\nNo other plugins under the `@babel/` namespace are impacted, but third-party plugins might be.\n\n**Users that only compile trusted code are not impacted.**\n\n### Patches\n\nThe vulnerability has been fixed in `@babel/traverse@7.23.2`.\n\nBabel 6 does not receive security fixes anymore (see [Babel's security policy](https://github.com/babel/babel/security/policy)), hence there is no patch planned for `babel-traverse@6`.\n\n### Workarounds\n\n- Upgrade `@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.\n- If you cannot upgrade `@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:\n - `@babel/plugin-transform-runtime` v7.23.2\n - `@babel/preset-env` v7.23.2\n - `@babel/helper-define-polyfill-provider` v0.4.3\n - `babel-plugin-polyfill-corejs2` v0.4.6\n - `babel-plugin-polyfill-corejs3` v0.8.5\n - `babel-plugin-polyfill-es-shims` v0.10.0\n - `babel-plugin-polyfill-regenerator` v0.5.3",
