{"schema_version":"1.7.3","id":"GHSA-67hx-6x53-jw92","published":"2023-10-16T13:55:36Z","modified":"2026-06-30T07:59:17.377319014Z","aliases":["CVE-2023-45133"],"related":["CGA-6j48-q922-m585"],"summary":"Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code","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","affected":[{"package":{"name":"@babel/traverse","ecosystem":"npm","purl":"pkg:npm/%40babel/traverse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.23.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/10/GHSA-67hx-6x53-jw92/GHSA-67hx-6x53-jw92.json"}},{"package":{"name":"@babel/traverse","ecosystem":"npm","purl":"pkg:npm/%40babel/traverse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.0.0-alpha.0"},{"fixed":"8.0.0-alpha.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/10/GHSA-67hx-6x53-jw92/GHSA-67hx-6x53-jw92.json"}},{"package":{"name":"babel-traverse","ecosystem":"npm","purl":"pkg:npm/babel-traverse"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"last_known_affected_version_range":"< 7.23.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/10/GHSA-67hx-6x53-jw92/GHSA-67hx-6x53-jw92.json"}}],"references":[{"type":"WEB","url":"https://github.com/babel/babel/security/advisories/GHSA-67hx-6x53-jw92"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45133"},{"type":"WEB","url":"https://github.com/babel/babel/pull/16033"},{"type":"WEB","url":"https://github.com/babel/babel/commit/b13376b346946e3f62fc0848c1d2a23223314c82"},{"type":"WEB","url":"https://babeljs.io/blog/2023/10/16/cve-2023-45133"},{"type":"PACKAGE","url":"https://github.com/babel/babel"},{"type":"WEB","url":"https://github.com/babel/babel/releases/tag/v7.23.2"},{"type":"WEB","url":"https://github.com/babel/babel/releases/tag/v8.0.0-alpha.4"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00026.html"},{"type":"WEB","url":"https://www.debian.org/security/2023/dsa-5528"}],"database_specific":{"cwe_ids":["CWE-184","CWE-697"],"github_reviewed":true,"github_reviewed_at":"2023-10-16T13:55:36Z","nvd_published_at":"2023-10-12T17:15:09Z","severity":"CRITICAL"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
