CVE-2023-26159: Follow-Redirects Follow Redirects

Medium severity, CVSS 6.1. EPSS: 0.8% chance of exploitation in the next 30 days.

Versions of the package follow-redirects before 1.15.4 are vulnerable to Improper Input Validation due to the improper handling of URLs by the url.parse() function. When new URL() throws an error, it can be manipulated to misinterpret the hostname. An attacker could exploit this weakness to redirect traffic to a malicious site, potentially leading to information disclosure, phishing attacks, or other security breaches.

Affected products

• Follow-Redirects Follow Redirects: before 1.15.4 (fixed in 1.15.4)
