CVE-2022-35948 Information

Description

undici is an HTTP/1.1 client written from scratch for Node.js.=< 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.
