{"id":"CVE-2026-61591","state":"PUBLISHED","title":"djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)","description":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, for 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). This issue is fixed in djust 1.0.7. State snapshots are signed; unsigned or forged snapshots are rejected on the back-navigation restore path. As a workaround, do not enable state snapshots; do not hold authorization/ownership state in public view attributes.","publishedAt":"2026-09-16T21:57:26.957Z","updatedAt":"2026-09-17T13:22:26.195Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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-c67v-vqrp-m5wj","https://github.com/djust-org/djust/releases/tag/v1.0.7"],"weaknesses":["CWE-345","CWE-915"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61591.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61591","state":"PUBLISHED","datePublished":"2026-09-16T21:57:26.957Z","dateUpdated":"2026-09-17T13:22:26.195Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T17:12:17.237Z"},"containers":{"cna":{"title":"djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)","descriptions":[{"lang":"en","value":"djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance.
