Mô tả

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.

Mô tả của NVD

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.
