Name of the Vulnerable Software and Affected Versions http-proxy-agent versions prior to 2.1.0

Description A flaw was found in http-proxy-agent where it passes an auth option to the Buffer constructor without proper sanitization. This could result in a Denial of Service through the usage of all available CPU resources and data exposure through an uninitialized memory leak in setups where an attacker could submit typed input to the auth parameter.

Recommendations For versions prior to 2.1.0, update to version 2.1.0 or later to resolve the issue. As a temporary workaround, consider restricting the input to the auth parameter to prevent potential exploitation.
