CVE-2024-28849 (opens in a new tab)How to fix?
Upgrade follow-redirects to version 1.15.6 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure due to the handling of the Proxy-Authorization header across hosts. When using a dependent library, it only clears the authorization header during cross-domain redirects but allows the proxy-authentication header, which contains credentials, to persist. This behavior may lead to the unintended leakage of credentials if an attacker can trigger a cross-domain redirect and capture the persistent proxy-authentication header.

'coOkie': 't=1'
