The contents of arbitrary files can be returned to the browser. By adding ?.svg with ?.wasm?init or with sec-fetch-dest: script header, the server.fs.deny restriction was able to bypass. This bypass is only possible if the file is smaller than build.assetsInlineLimit (default: 4kB) and when using Vite 6.0+. Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected. This vulnerability is fixed in 4.5.12, 5.4.17, 6.0.14, 6.1.4, and 6.2.5.","published":"2025-04-03T19:15:40.000Z","lastModified":"2026-06-17T09:10:29.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"},"cwe":["CWE-200","CWE-284"],"affected":[],"epss":{"score":0.40461,"percentile":0.9864,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 40.5%, higher than 99% of all known CVEs.
