• PyPI djust: < 1.0.7 → fixed in 1.0.7

Description

Impact 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). Patches Fixed in djust 1.0.7. State snapshots are signed; unsigned or forged snapshots are rejected on the back-navigation restore path. Workarounds Do not enable state snapshots; do not hold authorization/ownership state in public view attributes.
