Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, in a default dozzle deploy (the documented quickstart, no DOZZLEAUTHPROVIDER set), POST /api/notifications/test-webhook is reachable without authentication and forwards an attacker-controlled URL into a WebhookDispatcher that sends an HTTP POST to the supplied URL with attacker-controlled request headers, and returns the response status code AND up to 1MB of the response body to the caller, when the target replies non-2xx. This vulnerability is fixed in 10.5.2.
