Overview

github.com/pusher/oauth2_proxy is a reverse proxy that provides authentication with Google, Github or other providers.

Affected versions of this package are vulnerable to Open Redirect. The pattern '/\domain.com' is not disallowed when redirecting, allowing for open redirect. Authentication tokens could be silently harvested by an attacker.
