Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the notification subscription process when VAPID delivery is enabled. An attacker can cause the server to send outbound requests to arbitrary HTTPS endpoints by supplying a crafted endpoint URL during the subscription process. Notification metadata may be disclosed to the attacker-controlled endpoint through the encrypted web push request path.
Workaround
This vulnerability can be mitigated by disabling the push notifications feature by removing the VAPID keys from the server.
