Package	Affected versions	Patched versions
https-proxy-agent https-proxy-agent_project	`< 2.2.0`	`2.2.0`
https-proxy-agent npm	`< 2.2.0`	`2.2.0`

Description

Versions of https-proxy-agent before 2.2.0 are vulnerable to denial of service. This is due to unsanitized options (proxy.auth) being passed to Buffer().

Recommendation

Update to version 2.2.0 or later.

NVD description

https-proxy-agent before 2.1.1 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).
