An issue allows unauthenticated attackers with network access to perform server-side request forgery (SSRF), a technique where an attacker forces a server to make requests to an unintended location. By providing a malicious `uri` query parameter to the HTTP API, attackers can use `tcp://` or `unix://` URIs to override the configured backend and redirect connections to arbitrary targets. The affected endpoints include '/api/info', '/api/speech-to-text', and '/api/text-to-speech'.
