From 4.1.11 until 4.1.12 and 5.0.3, isFileLoadingAllowed and the filesystem read interpret backslashes differently on Windows in packages/mocker/src/node/interceptorPlugin.ts. When a client can reach the Vite dev server on Windows and register a redirect mock containing backslash traversal, POSIX joining preserves a Windows backslash traversal that the later filesystem read interprets as a path separator, so the client can read a file outside server.fs.allow that the Vitest process can access. This issue is fixed in versions 4.1.12 and 5.0.3.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9,"severity":null}],"references":["https://github.com/vitest-dev/vitest/security/advisories/GHSA-xp26-3454-mjgp","https://github.com/vitest-dev/vitest/commit/15cc006aa9f8683dc5f7e895d011fa7dc751ce35","https://github.com/vitest-dev/vitest/commit/b825313243dc55757e8d7c0f9e7a792135e13473","https://github.com/vitest-dev/vitest/releases/tag/v4.1.12","https://github.com/vitest-dev/vitest/releases/tag/v5.0.3"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-105152","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 20, 2026, 3:21:32 PM","dateUpdated":"Oct 28, 2026, 2:04:58 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
