CVE-2023-26159
Public on
Last Modified:
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.
Statement
follow-redirects is a transitive dependency of Grafana, and does not affect Red Hat Enterprise Linux 8.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
