{"id":"PYSEC-2026-4047","summary":"djust has an authorization bypass on the WebSocket/SSE mount path","details":"### Impact\nThe 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.\n\n### Patches\nFixed 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.\n\n### Workarounds\nGate views using djust's `login_required` / `permission_required` / `check_permissions` attributes (honored on all transports) rather than HTTP-only mixins/decorators.","aliases":["CVE-2026-61594","GHSA-xhhm-f6hp-2qwj"],"modified":"2026-10-01T17:45:04.657358852Z","published":"2026-10-01T16:38:31.739017Z","references":[{"type":"WEB","url":"https://github.com/djust-org/djust/security/advisories/GHSA-xhhm-f6hp-2qwj"},{"type":"PACKAGE","url":"https://github.com/djust-org/djust"},{"type":"WEB","url":"https://github.com/djust-org/djust/releases/tag/v1.0.7"},{"type":"PACKAGE","url":"https://pypi.org/project/djust"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-xhhm-f6hp-2qwj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61594"}],"affected":[{"package":{"name":"djust","ecosystem":"PyPI","purl":"pkg:pypi/djust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.7"}]}],"versions":["0.1.0","0.1.2","0.1.3","0.1.4","0.1.5","0.1.6","0.1.7","0.1.8","0.1.9","0.2.0","0.2.1","0.2.2","0.3.0","0.3.1","0.3.2","0.3.4","0.3.5","0.3.6","0.3.7","0.3.8","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.9.0","0.9.1","0.9.2","0.9.4","0.9.5","0.9.6","0.9.7","1.0.0","1.0.0rc11","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/djust/PYSEC-2026-4047.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
