CVE-2026-61591 Details
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.
A vulnerability in Djust, a Django library that offers reactive server-side rendering with high performance, allows for privilege escalation and state injection through unsigned state snapshots. In versions prior to 1.0.7, views that opted into state snapshots embedded an unsigned `state_json` in the client page. This `state_json` was restored as trusted view state upon reconnection, without any integrity check. As a result, a client could manipulate the `state_json` and inject arbitrary view attributes, such as altering `is_admin` status or modifying `account_id` and `balance` values. This exploitation could escalate privileges or tamper with business logic represented in public view attributes, which is a common pattern in Djust applications.
Users can upgrade to Djust version 1.0.7, where this vulnerability is fixed. In addition, as a general practice, avoid enabling state snapshots and do not store authorization or ownership-related information in public view attributes.
