Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: forwarded versions prior to 0.1.2

Description: The issue affects the forwarded module used by the Express.js framework to handle the X-Forwarded-For header. It is susceptible to a regular expression denial of service when passed specially crafted input to parse, causing the event loop to be blocked and resulting in a denial of service condition.

Recommendations: Update to version 0.1.2 or later. As a temporary workaround, consider restricting the input to the forwarded module to minimize the risk of exploitation.
