{"id":"GHSA-8gvc-j273-4wm5","summary":"Vitest browser mode serves arbitrary files","details":"### Summary\n`__screenshot-error` handler on the browser mode HTTP server that responds any file on the file system. Especially if the server is exposed on the network by [`browser.api.host: true`](https://vitest.dev/guide/browser/config.html#browser-api), an attacker can send a request to that handler from remote to get the content of arbitrary files.\n\n### Details\nThis `__screenshot-error` handler on the browser mode HTTP server responds any file on the file system.\nhttps://github.com/vitest-dev/vitest/blob/f17918a79969d27a415f70431e08a9445b051e45/packages/browser/src/node/plugin.ts#L88-L130\n\nThis code was added by https://github.com/vitest-dev/vitest/commit/2d62051f13b4b0939b2f7e94e88006d830dc4d1f.\n\n### PoC\n1. Create a directory and change the current directory to that directory\n1. Run `npx vitest init browser`\n1. Run `npm run test:browser`\n2. Run `curl http://localhost:63315/__screenshot-error?file=/path/to/any/file`\n\n### Impact\nUsers explicitly exposing the browser mode server to the network by [`browser.api.host: true`](https://vitest.dev/guide/browser/config.html#browser-api) may get any files exposed.","aliases":["CVE-2025-24963"],"modified":"2025-02-04T22:03:47Z","published":"2025-02-04T16:51:08Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-02-04T16:51:08Z","nvd_published_at":"2025-02-04T20:15:50Z","cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/vitest-dev/vitest/security/advisories/GHSA-8gvc-j273-4wm5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-24963"},{"type":"WEB","url":"https://github.com/vitest-dev/vitest/commit/2d62051f13b4b0939b2f7e94e88006d830dc4d1f"},{"type":"WEB","url":"https://github.com/vitest-dev/vitest/commit/ed9aeba212df04b83ed01810780663ff2cdd0adf"},{"type":"PACKAGE","url":"https://github.com/vitest-dev/vitest"},{"type":"WEB","url":"https://github.com/vitest-dev/vitest/blob/f17918a79969d27a415f70431e08a9445b051e45/packages/browser/src/node/plugin.ts#L88-L130"},{"type":"WEB","url":"https://vitest.dev/guide/browser/config.html#browser-api"}],"affected":[{"package":{"name":"@vitest/browser","ecosystem":"npm","purl":"pkg:npm/%40vitest/browser"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.4"},{"fixed":"2.1.9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/02/GHSA-8gvc-j273-4wm5/GHSA-8gvc-j273-4wm5.json"}},{"package":{"name":"@vitest/browser","ecosystem":"npm","purl":"pkg:npm/%40vitest/browser"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.0.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/02/GHSA-8gvc-j273-4wm5/GHSA-8gvc-j273-4wm5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
