Overview

djust is a Phoenix LiveView-style reactive components for Django with Rust-powered performance. Real-time UI updates over WebSocket, no JavaScript build step required.

Affected versions of this package are vulnerable to Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') via the handle_mount process in the WebSocket and SSE view-mount path. An attacker can trigger execution of arbitrary importable modules' top-level code by sending a crafted frame specifying a module path, leading to server-side code execution, denial of service through import bombs or expensive dependency trees, and information disclosure via error messages.
