From 3.0.0 until 3.2.5, 4.1.8, and 5.0.0-beta.4, Vitest Browser Mode exposed a cdp() API that forwarded raw Chrome DevTools Protocol methods without being gated by allowWrite or allowExec, allowing a remote client with exposed browser API metadata to use CDP Page.setDownloadBehavior and Runtime.evaluate to overwrite vite.config.ts and execute attacker-controlled Node.js code. This issue is fixed in versions 3.2.5, 4.1.8, and 5.0.0-beta.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-749","CWE-862"],"references":["https://github.com/vitest-dev/vitest/commit/385a1aefd4c2bfa5e7d58bf7c6834c929969f2c7","https://github.com/vitest-dev/vitest/commit/63e3b2eee4d58da56786a6333f517b9b492528c7","https://github.com/vitest-dev/vitest/commit/e4067b3b150005fd42cf75f994300119245806b9","https://github.com/vitest-dev/vitest/pull/10444","https://github.com/vitest-dev/vitest/pull/10450"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-53633","score":0.00896,"percentile":0.59282,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-g8mr-85jm-7xhm","url":"https://osv.dev/vulnerability/GHSA-g8mr-85jm-7xhm","summary":"Vitest Browser: Exposed Browser Mode API Can Proxy CDP and Overwrite Config Files, Leading to RCE","modified":"2026-08-13T18:30:12.338998545Z","packages":[{"ecosystem":"npm","name":"@vitest/browser","purl":"pkg:npm/%40vitest/browser","ranges":[">=5.0.0-beta.0 <5.0.0-beta.4"],"fixed":["5.0.0-beta.4"]},{"ecosystem":"npm","name":"@vitest/browser","purl":"pkg:npm/%40vitest/browser","ranges":[">=4.0.0 <4.1.8"],"fixed":["4.1.8"]},{"ecosystem":"npm","name":"@vitest/browser","purl":"pkg:npm/%40vitest/browser","ranges":[">=3.0.0 <3.2.5"],"fixed":["3.2.5"]},{"ecosystem":"npm","name":"vite-plus","purl":"pkg:npm/vite-plus","ranges":["<0.1.24"],"fixed":["0.1.24"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
