Описание
Authorization headers are cleared on cross-origin redirect. However, cookie headers which are sensitive headers and are official headers found in the spec, remain uncleared. There are active users using cookie headers in undici. 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. This was patched in v5.7.1. By default, this vulnerability is not exploitable. Do not enable redirections, i.e. maxRedirections: 0 (the default).
A flaw was found in the undici package. After cookie headers are set, they are not cleared. This issue could allow an attacker to take advantage of this cookie, which could be used to control the redirection target.
Меры по смягчению последствий
By default, this vulnerability is not exploitable. In order to make sure this is mitigated, do not enable redirections, i.e.: maxRedirections: 0
