CVE-2026-61591

djust: Unsigned client state snapshot is restored as trusted view state (privilege escalation / state injection)

Published Sep 16, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
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.
