- Summary
- djust: WebSocket/runtime reconstructed request omits the client Host, causing host/subdomain TenantResolvers to misresolve the tenant on the live path
- Details
-
djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. Prior to version 1.0.7, the WebSocket
handle_mountandViewRuntime._build_requestrebuild anHttpRequestviaRequestFactory().get(...)with noHTTP_HOST, sorequest.get_host()defaulted to"testserver"on the live path. Host/subdomain/domainTenantResolvers then misresolved the tenant —Noneon the live path while the HTTP path resolved correctly. WithSTRICT_MODE=Falsethe tenant-scoped managers returned unscoped rows (cross-tenant disclosure); with the default they returned an empty queryset (broken tenancy). This is fixed in djust 1.0.7. The handshake Host is extracted from the ASGI scope, validated againstALLOWED_HOSTS(the same logic as the CSWSH Origin gate, parsed with Django'ssplit_domain_portso malformed Hosts are rejected at the boundary), and propagated — with the TLS scheme — into the reconstructed request, so live-path tenant resolution matches HTTP exactly. There is no known workaround on the live path short of upgrading. Users are most exposed when combined withSTRICT_MODE=False. - Database specific
