Injection via Content-Type", "summary": "### Impact\n\n`=< 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.\n\nExample:\n\n```\nimport { request } from 'undici'\n\nconst unsanitizedContentTypeInput = 'application/json\\r\\n\\r\\nGET /foo2 HTTP/1.1'\n\nawait request('http://localhost:3000, {\n method: 'GET',\n headers: {\n 'content-type': unsanitizedContentTypeInput\n },\n})\n```\n\nThe above snippet will perform two requests in a single `request` API call:\n\n1) `http://localhost:3000/`\n2) `http://localhost:3000/foo2`\n\n### Patches\n\nThis issue was patched in Undici v5.8.1\n\n### Workarounds\n\nSanitize input when sending content-type headers using user input.\n\n## For more information\nIf you have any questions or comments about this advisory:\n\n- Open an issue in [undici repository](https://github.com/nodejs/undici/issues)\n- To make a
