Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of djust before 1.0.7 have a multi-tenant isolation flaw on the WebSocket and SSE path: the current tenant is never set there, so the tenant-aware queryset returns unfiltered results and exposes other tenants' rows to anyone holding a live connection. The source gives few details on the exact preconditions beyond the connection itself. Upgrade to djust 1.0.7, which fixes the issue; no workaround is listed for the live path.
