Details

Nodejs ‘undici’ vulnerable to CRLF Injection via Content-Type ### Impact `=< 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` ### Patches This issue was patched in Undici v5.8.1 ### Workarounds Sanitize input when sending content-type headers using user input. ## For more information If you have any questions or comments about this advisory: - Open an issue in [undici repository](https://github.com/nodejs/undici/issues) - To make a report, follow the [SECURITY](https://github.com/nodejs/node/blob/HEAD/SECURITY.md) document
