   "title": "Undici has CRLF Injection in undici via `upgrade` option",
   "summary": "### Impact\n\nWhen an application passes user-controlled input to the `upgrade` option of `client.request()`, an attacker can inject CRLF sequences (`\\r\\n`) to:\n\n1. Inject arbitrary HTTP headers\n2. Terminate the HTTP request prematurely and smuggle raw data to non-HTTP services (Redis, Memcached, Elasticsearch)\n\nThe vulnerability exists because undici writes the `upgrade` value directly to the socket without validating for invalid header characters:\n\n```javascript\n// lib/dispatcher/client-h1.js:1121\nif (upgrade) {\n  header += `connection: upgrade\\r\\nupgrade: ${upgrade}\\r\\n`\n}\n```\n\n### Patches\n\n Patched in the undici version v7.24.0 and v6.24.0. Users should upgrade to this version or later.\n\n### Workarounds\n\nSanitize the `upgrade` option string before passing to undici:\n\n```javascript\nfunction sanitizeUpgrade(value) {\n  if (/[\\r\\n]/.test(value)) {\n    throw new Error('Invalid upgrade value')\n  }\n  return value\n}\n\nclient.request({\n  upgrade: sanitizeUpgrade(userInput)\n})\n```",
