A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 1.0.7
Patched in 1.0.7
Details
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).
Fixed in djust 1.0.7. State snapshots are signed; unsigned or forged snapshots are rejected on the back-navigation restore path.
Do not enable state snapshots; do not hold authorization/ownership state in public view attributes.
EPSS, exploit probability
Low0.22%
estimated chance of real-world exploitation in the next 30 days, higher than 13.3% of every CVE FIRST.org scores
Refreshed 11/1/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
