{"id":"CVE-2023-34238","aliases":["GHSA-c6f8-8r25-c4gc"],"url":"https://o3.security/vulnerability/CVE-2023-34238","summary":" Local File Inclusion vulnerability in Gatsby","details":"Gatsby is a free and open source framework based on React. The Gatsby framework prior to versions 4.25.7 and 5.9.1 contain a Local File Inclusion vulnerability in the `__file-code-frame` and `__original-stack-frame` paths, exposed when running the Gatsby develop server (`gatsby develop`). Any file in scope of the development server could potentially be exposed. It should be noted that by default `gatsby develop` is only accessible via the localhost `127.0.0.1`, and one would need to intentionally expose the server to other interfaces to exploit this vulnerability by using server options such as `--host 0.0.0.0`, `-H 0.0.0.0`, or the `GATSBY_HOST=0.0.0.0` environment variable. A patch has been introduced in `gatsby@5.9.1` and `gatsby@4.25.7` which mitigates the issue. Users are advised to upgrade. Users unable to upgrade should avoid exposing their development server to the internet.","published":"2023-06-07T23:24:49.724Z","modified":"2026-07-15T01:49:11.845727529Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"gatsby","fixedVersion":"4.25.7"},{"ecosystem":"npm","name":"gatsby","fixedVersion":"5.9.1"}],"fix":{"url":"https://github.com/gatsbyjs/gatsby/commit/ae5a654eb346b2e7a9d341b809b2f82d34c0f17c","label":"gatsbyjs/gatsby@ae5a654"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/34xxx/CVE-2023-34238.json"},{"type":"ADVISORY","url":"https://github.com/gatsbyjs/gatsby/security/advisories/GHSA-c6f8-8r25-c4gc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34238"},{"type":"FIX","url":"https://github.com/gatsbyjs/gatsby/commit/ae5a654eb346b2e7a9d341b809b2f82d34c0f17c"},{"type":"FIX","url":"https://github.com/gatsbyjs/gatsby/commit/fc22f4ba3ad7ca5fb3592f38f4f0ca8ae60b4bf7"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:11.845727529Z"}}
