- Summary
- Client mass-assignment of arbitrary view attributes via the default dj-model update_model handler
- Details
-
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7,
djust.mixins.model_binding.ModelBindingMixinprovides a defaultupdate_modelevent handler and is part of the LiveView base MRO, so every LiveView exposes it. Itsetattrs a view attribute whose name is client-supplied (field), gated only by: reject_-prefixed names; reject a 14-entry denylist of framework internals (FORBIDDEN_MODEL_FIELDS); optionalallowed_model_fieldswhich defaults to None = allow all; andhasattrexistence. As a result, a client can set any public, existing view attribute — not just the fields actually bound withdj-model=in the rendered template. The denylist covers framework plumbing but nothing about developer business/authz state, and the allowlist is opt-in (off by default). A developer who binds onedj-model="search"input and also keepsself.account_id/self.is_admin/self.total_priceas view state does not realize a client can set ALL of them via{type:event, event:"update_model", params:{field, value}}over the WebSocket. Type coercion matches the target attribute's type (so"true"-> bool True), aiding the attacker. This issue is fixed in djust 1.0.7. As a workaround, setallowed_model_fieldsexplicitly on every view using dj-model (or subclassing LiveView) to the minimal list of bindable fields; do not keep authorization/ownership state in public view attributes that share the view with dj-model bindings. - Database specific
