{"id":"GHSA-j2wh-wrv3-4x4g","summary":"Unwanted access to the entire file system vulnerability due to a missing check in `staticFiles` HTTP handler","details":"### Summary\nMissing check vulnerability in the static file handler allows any client to access the files in the server's file system\n\n### Details\nWhen `staticFiles` is set in the `serve` settings in the configuration file, the following handler doesn't check if `absolutePath` is still under the directory provided as `staticFiles`;\n\n```ts\n  if (staticFiles) {\n    router.get('/:relativePath+', async request =\u003e {\n      let { relativePath } = request.params;\n      if (!relativePath) {\n        relativePath = 'index.html';\n      }\n      const absolutePath = path.join(baseDir, staticFiles, relativePath);\n      if (absolutePath.includes(staticFiles) && (await pathExists(absolutePath))) {\n        const readStream = fs.createReadStream(absolutePath);\n        return new Response(readStream as any, {\n          status: 200,\n        });\n      }\n      return undefined;\n    });\n ```\n\n### Example scenario\nTo reproduce it, set `staticFiles` to the relative path of a directory in `.meshrc.yml`;\n\n```yml\nserve:\n   staticFiles: ./public\n```\n\nThen start the server with `mesh dev`, and browse to `/..%2fpackage.json` then you will see the content of `package.json`. You can even go deeper to see sensitive data; `/..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2fetc/passwd`\n\n### Impact and solution\nIf `staticFiles` is set under `serve` in the configuration file. you have two options to fix vulnerability;\n\n- Update `@graphql-mesh/cli` to a version higher than `0.82.21`, and if you use `@graphql-mesh/http`, update it to a version higher than `0.3.18`\n- Remove `staticFiles` option from the configuration, and use other solutions to serve static files.\n\n### Credits\nThanks [alanwillms@gmail.com](mailto:alanwillms@gmail.com) for reporting this vulnerability with details","aliases":["CVE-2025-27098"],"modified":"2025-02-20T23:12:14.649413Z","published":"2023-02-16T18:41:07Z","database_specific":{"nvd_published_at":"2025-02-20T21:15:26Z","cwe_ids":["CWE-22"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-02-16T18:41:07Z"},"references":[{"type":"WEB","url":"https://github.com/Urigo/graphql-mesh/security/advisories/GHSA-j2wh-wrv3-4x4g"},{"type":"WEB","url":"https://github.com/ardatan/graphql-mesh/security/advisories/GHSA-j2wh-wrv3-4x4g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27098"},{"type":"WEB","url":"https://github.com/Urigo/graphql-mesh/commit/95d93e7c140c2995b37e9d822aa3fe4e24ed2e78"},{"type":"PACKAGE","url":"https://github.com/Urigo/graphql-mesh"}],"affected":[{"package":{"name":"@graphql-mesh/cli","ecosystem":"npm","purl":"pkg:npm/%40graphql-mesh/cli"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.78.0"},{"fixed":"0.82.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/02/GHSA-j2wh-wrv3-4x4g/GHSA-j2wh-wrv3-4x4g.json"}},{"package":{"name":"@graphql-mesh/http","ecosystem":"npm","purl":"pkg:npm/%40graphql-mesh/http"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.3.19"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/02/GHSA-j2wh-wrv3-4x4g/GHSA-j2wh-wrv3-4x4g.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:L"}]}
