Description

An Improper Input Validation flaw was found in follow-redirects due to the improper handling of URLs by the url.parse() function. When a new URL() throws an error, it can be manipulated to misinterpret the hostname. This issue could allow an attacker to redirect traffic to a malicious site, potentially leading to information disclosure, phishing attacks, or other security breaches.
