CyberRota Analysis
AI-GeneratedThe vulnerability affects the LiveViewConsumer component of the djust library, allowing unauthorized clients to bypass authentication and authorization checks after a failed LiveView mount. This can lead to unauthorized access to sensitive data and operations through the execution of event handlers without a valid session. Organizations using djust prior to version 1.0.4 should prioritize upgrading to mitigate the risk of unauthorized data exposure and manipulation.

Original NVD Description
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to 1.0.4, LiveViewConsumer.handle_mount sends a `{"type":"navigate","to":...}` frame when login_required, permission_required, or a redirecting on_mount hook denies a LiveView mount, but returns without closing the WebSocket or clearing self.view_instance. A browser follows the redirect, but a raw WebSocket client can ignore it and retain the mounted socket. Because LiveViewConsumer.handle_event does not recheck authentication or authorization, the client can send `{"type":"event",...}` frames that invoke @event_handler methods without an authenticated session, including through handle_live_redirect_mount, enabling unauthorized sensitive reads or mutations. This issue is fixed in version 1.0.4.
