Nodejs ‘undici’ vulnerable to CRLF Injection via Content-Type
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
`=< [email protected]` 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.
