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.

Description Laura Pardo 2018-04-13 16:05:23 UTC

A flaw was found in http-proxy-agent versions before 2.1.0. The http-proxy-agent passes auth option to the Buffer constructor without proper sanitization, resulting in DoS and uninitialized memory leak in setups where an attacker could submit typed input to the 'auth' parameter (e.g. JSON).
