{"id":"CVE-2023-45133","state":"PUBLISHED","title":"Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code","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/traverse@7.23.2` and `@babel/traverse@8.0.0-alpha.4`. Those who cannot upgrade `@babel/traverse` and are using one of the affected packages mentioned above should 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` v0.4.3, `babel-plugin-polyfill-corejs2` v0.4.6, `babel-plugin-polyfill-corejs3` v0.8.5, `babel-plugin-polyfill-es-shims` v0.10.0, `babel-plugin-polyfill-regenerator` v0.5.3.","publishedAt":"2023-10-12T16:17:08.624Z","updatedAt":"2025-02-13T17:13:48.413Z","severity":{"score":9.4,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["babel babel"],"affected":[{"vendor":"babel","product":"babel","versions":[{"version":"< 7.23.2","status":"affected"},{"version":">= 8.0.0-alpha.0, < 8.0.0-alpha.4","status":"affected"}]}],"references":["https://github.com/babel/babel/security/advisories/GHSA-67hx-6x53-jw92","https://github.com/babel/babel/pull/16033","https://github.com/babel/babel/commit/b13376b346946e3f62fc0848c1d2a23223314c82","https://github.com/babel/babel/releases/tag/v7.23.2","https://github.com/babel/babel/releases/tag/v8.0.0-alpha.4","https://www.debian.org/security/2023/dsa-5528","https://lists.debian.org/debian-lts-announce/2023/10/msg00026.html"],"weaknesses":["CWE-184"],"ingestedAt":"2026-10-29T20:06:24.729Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/45xxx/CVE-2023-45133.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-45133","state":"PUBLISHED","datePublished":"2023-10-12T16:17:08.624Z","dateUpdated":"2025-02-13T17:13:48.413Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-10-04T16:02:46.328Z"},"containers":{"cna":{"title":"Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code","descriptions":[{"lang":"en","value":"Babel is a compiler for writingJavaScript.
