GHSA-q768-x9m6-m9qp
undici before v5.8.0 vulnerable to uncleared cookies on cross-host / cross-origin redirect
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### 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).
