CVE-2026-61588
djust's Django model serialization has no sensitive-field denylist: password hashes, privilege flags, and PII on a public view attribute are sent to the client
Description
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, when a Django `Model` instance is assigned to a public view attribute, djust serialized it to the client with no sensitive-field denylist — sending fields such as `password` (the hash), privilege flags (e.g. `is_staff` / `is_superuser`), tokens, and other PII to the browser. Because exposing model objects to templates is a normal djust pattern, this could leak credentials/PII without the developer realizing the full object crossed the wire. This is fixed in djust 1.0.7. Model serialization applies a secure-by-default sensitive-field denylist (password/hash/token/secret-style fields and known privilege flags are withheld) with an identity-subset fallback. As a workaround, keep `Model` instances on `_private` attributes and expose only the specific fields needed, until patched.
