CVE-2026-61592 Details
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.
A session hijacking vulnerability exists in djust versions prior to 1.0.7. The issue arises because Server-Sent Events (SSE) sessions were solely based on a client-selected session_id, without any association to the authenticated user. This lack of binding, which is present in the WebSocket transport, allows an attacker to exploit the vulnerability. If a session_id is learned or leaked, the attacker can connect to the message endpoint and trigger event handlers that operate under the victim's identity and state.
Users can upgrade to djust version 1.0.7, which binds each SSE session to the authenticated user and prevents cross-principal access. Alternatively, the SSE transport can be disabled until the upgrade is performed.
