|
|
"summary": "### Impact\n\n`undici` is vulnerable to SSRF (Server-side Request Forgery) when an application takes in **user input** into the `path/pathname` option of `undici.request`.\n\nIf a user specifies a URL such as `http://127.0.0.1` or `//127.0.0.1`\n\n```js\nconst undici = require(\"undici\")\nundici.request({origin: \"http://example.com\", pathname: \"//127.0.0.1\"})\n```\n\nInstead of processing the request as `http://example.org//127.0.0.1` (or `http://example.org/http://127.0.0.1` when `http://127.0.0.1 is used`), it actually processes the request as `http://127.0.0.1/` and sends it to `http://127.0.0.1`.\n\nIf a developer passes in user input into `path` parameter of `undici.request`, it can result in an _SSRF_ as they will assume that the hostname cannot change, when in actual fact it can change because the specified path parameter is combined with the base URL.\n\n### Patches\n\nThis issue was fixed in `undici@5.8.1`.\n\n### Workarounds\n\nThe best workaround is to validate user input before passing it to the `undici.request` call.\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 report, follow the [SECURITY](https://github.com/nodejs/node/blob/HEAD/SECURITY.md) document\n",
