{"id":"PYSEC-2026-4041","summary":"djust has broken object-level access control (IDOR)","details":"### Impact\ndjust's per-object authorization (`get_object` + `has_object_permission`, ADR-017) was enforced on the WebSocket **mount** and **event** paths but **not** on three other render entry points: (a) the initial **HTTP GET** render, (b) **SPA `url_change`** navigation, and (c) `{% live_render %}` **embedded child** views. An authenticated user could therefore view (and on some paths act on) an object they are not authorized for by loading the page directly, navigating to it via SPA url-change, or composing it as an embedded child — a classic IDOR / broken object-level access control on object-scoped views.\n\n### Patches\nFixed in **djust 1.0.7**. All render entry points now route through a shared `enforce_object_permission` chokepoint: HTTP GET returns **403**, `url_change` emits a `permission_denied` frame and skips the render, and `{% live_render %}` (eager + lazy) refuses the embed. Views without a custom `get_object` are unaffected (no-op).\n\n### Workarounds\nNo reliable workaround short of upgrading. Do not expose object-scoped views through the HTTP-GET / url_change / live_render paths until patched.","aliases":["CVE-2026-61596","GHSA-c7c5-5j6r-q957"],"modified":"2026-10-01T17:45:03.811090149Z","published":"2026-10-01T16:38:31.975628Z","references":[{"type":"WEB","url":"https://github.com/djust-org/djust/security/advisories/GHSA-c7c5-5j6r-q957"},{"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-c7c5-5j6r-q957"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61596"}],"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-2026-4041.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}
