    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the proxy process.

    ##Mitigation

    1. Restricting the proxy to trusted origins or authentication

    2. whitelisting allowed target hosts

    3. Preventing access to link-local and internal IP ranges

    4. Removing support for unsafe HTTP methods/headers

    5. Enabling cloud provider mitigations

    6. Deploying network-level protections.
