{"id":"CVE-2026-61594","state":"PUBLISHED","title":"djust has an authorization bypass on the WebSocket/SSE mount path","description":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the live (WebSocket) transport authorizes a mount via `check_view_auth`, not Django's `View.dispatch()` chain. As a result, standard Django authorization — `LoginRequiredMixin`, `PermissionRequiredMixin`, `UserPassesTestMixin`, `@method_decorator(login_required, name=\"dispatch\")`, and custom `dispatch()` guards — and the djust admin extension's staff gate (applied only in the HTTP `as_view` wrapper) were enforced on the initial HTTP GET but silently bypassed over WebSocket, where all events and state flow. An anonymous or under-privileged client could open a WebSocket and mount such a view — including admin list/create/change/delete — and dispatch its handlers. This is fixed in djust 1.0.7. `check_view_auth` now honors the Django `AccessMixin` family on every transport; a new system check S004 fails loud at startup on auth patterns the runtime cannot safely replay (decorator/overridden-`dispatch` forms); and the admin base mixin declares `login_required = True` + an active-staff `check_permissions` gate. As a workaround, gate views using djust's `login_required` / `permission_required` / `check_permissions` attributes (honored on all transports) rather than HTTP-only mixins/decorators.","publishedAt":"2026-09-16T21:59:01.907Z","updatedAt":"2026-09-17T14:39:07.324Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["djust-org djust"],"affected":[{"vendor":"djust-org","product":"djust","versions":[{"version":"< 1.0.7","status":"affected"}]}],"references":["https://github.com/djust-org/djust/security/advisories/GHSA-xhhm-f6hp-2qwj","https://github.com/djust-org/djust/releases/tag/v1.0.7"],"weaknesses":["CWE-306","CWE-862"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61594.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61594","state":"PUBLISHED","datePublished":"2026-09-16T21:59:01.907Z","dateUpdated":"2026-09-17T14:39:07.324Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T17:12:17.238Z"},"containers":{"cna":{"title":"djust has an authorization bypass on the WebSocket/SSE mount path","descriptions":[{"lang":"en","value":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance.
