Details

undici before v5.8.0 vulnerable to uncleared cookies on cross-host / cross-origin redirect ### Impact Authorization headers are already cleared on cross-origin redirect in https://github.com/nodejs/undici/blob/main/lib/handler/redirect.js#L189, based on https://github.com/nodejs/undici/issues/872. However, cookie headers which are sensitive headers and are official headers found in the spec, remain uncleared. There also has been active discussion of implementing a cookie store https://github.com/nodejs/undici/pull/1441, which suggests that there are active users using cookie headers in undici. As such this may lead to accidental leakage of cookie to a 3rd-party site or a malicious attacker who can control the redirection target (ie. an open redirector) to leak the cookie to the 3rd party site. ### Patches This was patched in v5.8.0. ### Workarounds By default, this vulnerability is not exploitable. Do not enable redirections, i.e. `maxRedirections: 0` (the default). ### References https://hackerone.com/reports/1635514 https://curl.se/docs/CVE-2018-1000007.html https://curl.se/docs/CVE-2022-27776.html ### 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
