{"id":"PYSEC-2026-4040","summary":"djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)","details":"### Impact\nFor views that opt into state snapshots, the snapshot `state_json` embedded in the client page was restored on reconnect as **trusted** view state with no integrity check. A client could edit the unsigned `state_json` in their page and return it in the reconnect mount frame to **inject arbitrary view attributes** — e.g. flip `is_admin` to `True`, or change `account_id` / `balance` — escalating privilege or tampering with business state held in public view attributes (the normal djust pattern).\n\n### Patches\nFixed in **djust 1.0.7**. State snapshots are signed; unsigned or forged snapshots are rejected on the back-navigation restore path.\n\n### Workarounds\nDo not enable state snapshots; do not hold authorization/ownership state in public view attributes.","aliases":["CVE-2026-61591","GHSA-c67v-vqrp-m5wj"],"modified":"2026-10-01T17:45:03.797138777Z","published":"2026-10-01T16:38:31.625008Z","references":[{"type":"WEB","url":"https://github.com/djust-org/djust/security/advisories/GHSA-c67v-vqrp-m5wj"},{"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-c67v-vqrp-m5wj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61591"}],"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-2026-4040.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:H/A:N"}]}
