{"id":"DEBIAN-CVE-2022-35948","details":"undici is an HTTP/1.1 client, written from scratch for Node.js.`=\u003c undici@5.8.0` users are vulnerable to _CRLF Injection_ on headers when using unsanitized input as request headers, more specifically, inside the `content-type` header. Example: ``` import { request } from 'undici' const unsanitizedContentTypeInput = 'application/json\\r\\n\\r\\nGET /foo2 HTTP/1.1' await request('http://localhost:3000, { method: 'GET', headers: { 'content-type': unsanitizedContentTypeInput }, }) ``` The above snippet will perform two requests in a single `request` API call: 1) `http://localhost:3000/` 2) `http://localhost:3000/foo2` This issue was patched in Undici v5.8.1. Sanitize input when sending content-type headers using user input as a workaround.","modified":"2026-09-01T20:03:17.045538361Z","published":"2022-08-15T11:21:38.353Z","upstream":["CVE-2022-35948"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-35948"}],"affected":[{"package":{"name":"node-undici","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-undici?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.8.2+dfsg1+~cs18.9.18.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-35948.json"}},{"package":{"name":"node-undici","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-undici?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.8.2+dfsg1+~cs18.9.18.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-35948.json"}},{"package":{"name":"node-undici","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-undici?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.8.2+dfsg1+~cs18.9.18.1-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2022-35948.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
