Summary
undici before v5.8.0 vulnerable to uncleared cookies on cross-host / cross-origin redirect
Details

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).
