AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
Cross-origin CSRF: no attacker auth (PR:N) but victim must visit a malicious page (UI:R); same-origin policy blocks reading the SSE response (C:N), while state-changing handlers give I:H.

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the SSE client→server POST endpoints are @csrf_exempt and the SSE GET stream endpoint had no Origin check, so a cross-origin page could drive a victim-cookie-authenticated SSE session: force the victim's browser to GET the stream URL (which creates and mounts a LiveView as the victim) and POST to the message endpoint with credentials: include to fire state-changing event handlers as the victim. The URL session_id is client-chosen (validated only for UUID *format*), so it is not a CSRF token, and a JSON body sent as text/plain is a CORS simple request with no preflight. The issue is fixed in 1.0.7. All three SSE endpoints validate the request Origin against ALLOWED_HOSTS (mirroring the WebSocket CSWSH defense) and reject cross-origin requests with 403; the POST endpoints additionally require Content-Type: application/json (415 otherwise), closing the text/plain simple-request bypass. As a workaround, disable the SSE transport, or front it with a proxy that enforces an Origin allowlist.
AnalysisAI
Cross-site request forgery in djust's Server-Sent-Events transport affects all versions prior to 1.0.7 and allows a cross-origin attacker page to drive a victim's cookie-authenticated SSE session, firing state-changing LiveView event handlers as that victim. Remote attackers need no authentication of their own, but exploitation requires the victim to be lured to an attacker-controlled page while holding an active authenticated djust session and while the SSE transport is enabled (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N - integrity impact only, no confidentiality or availability impact). …

Vulnerability AssessmentAI
| Exploitation | Requires djust < 1.0.7 with the SSE transport in use (the affected client→server POST endpoints are @csrf_exempt and the GET stream endpoint lacks an Origin check). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine, well-characterized CSRF (CWE-352) on djust's Server-Sent-Events transport. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade djust to version 1.0.7 or later, which is the vendor-released patch: in that release all three SSE endpoints validate the request Origin against ALLOWED_HOSTS and return 403 for cross-origin requests, and the client→server POST endpoints require Content-Type: application/json and return 415 otherwise. … Detailed patch versions, workarounds, and compensating controls in full report. |
