CyberRota Analysis

AI-Generated

The DSSRF Node.js library prior to version 1.0.5 is vulnerable to server-side request forgery (SSRF) due to improper handling of localhost addresses when the DNS resolver returns NXDOMAIN. This flaw can allow attackers to exploit the library's functionality to make unauthorized requests to internal services. Developers and organizations using this library should prioritize upgrading to version 1.0.5 to mitigate potential security risks.

Original NVD Description

DSSRF is a Node.js library that provides a wide range of utilities and advanced SSRF defense checks. Prior to 1.0.5, is_url_safe can treat localhost as safe when DNS resolver 1.1.1.1 returns NXDOMAIN because dns.resolve4 yields no address and no dns.lookup fallback occurs, allowing server-side request forgery. This issue is fixed in version 1.0.5.
