Sources and claim methodology

Upstream source description

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, djust's per-object authorization (`get_object` + `has_object_permission`, ADR-017) was enforced on the WebSocket mount and event paths but not on three other render entry points: (a) the initial HTTP GET render, (b) SPA `url_change` navigation, and (c) `{% live_render %}` embedded child views. An authenticated user could therefore view (and on some paths act on) an object they are not authorized for by loading the page directly, navigating to it via SPA url-change, or composing it as an embedded child — a classic IDOR / broken object-level access control on object-scoped views. This is fixed in djust 1.0.7. All render entry points now route through a shared `enforce_object_permission` chokepoint: HTTP GET returns 403, `url_change` emits a `permission_denied` frame and skips the render, and `{% live_render %}` (eager + lazy) refuses the embed. Views without a custom `get_object` are unaffected (no-op). No reliable workaround short of upgrading. Do not expose object-scoped views through the HTTP-GET / url_change / live_render paths until patched.
