Sources and claim methodology

Upstream source description

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, SSE sessions were keyed solely by a client-chosen `session_id` with no binding to the authenticated user — a control the WebSocket transport has but that was dropped on SSE. An attacker who learns (or a victim who leaks) a `session_id` could connect to the message endpoint and dispatch event handlers that execute with the victim's identity and state. This is fixed in djust 1.0.7. Each SSE session is bound to its owning principal at creation and cross-principal access is rejected; SSE session creation is additionally capped per principal. As a workaround, disable the SSE transport.
