{"cve":"CVE-2026-61591","nvd":{"published":"2026-09-16T22:17:02.763","modified":"2026-09-30T17:51:56.193","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-345","CWE-915"],"references":["https://github.com/djust-org/djust/releases/tag/v1.0.7","https://github.com/djust-org/djust/security/advisories/GHSA-c67v-vqrp-m5wj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-61591","score":0.00225,"percentile":0.1308,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c67v-vqrp-m5wj","url":"https://osv.dev/vulnerability/GHSA-c67v-vqrp-m5wj","summary":"djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)","modified":"2026-10-01T17:55:55.790656064Z","packages":[{"ecosystem":"PyPI","name":"djust","purl":"pkg:pypi/djust","ranges":["<1.0.7"],"fixed":["1.0.7"]}]},{"id":"PYSEC-2026-4040","url":"https://osv.dev/vulnerability/PYSEC-2026-4040","summary":"djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)","modified":"2026-10-01T17:45:03.797138777Z","packages":[{"ecosystem":"PyPI","name":"djust","purl":"pkg:pypi/djust","ranges":["<1.0.7"],"fixed":["1.0.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
