Machine-written summary

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

djust before 1.0.7 rebuilds requests on its WebSocket live path without the client Host, so host- or subdomain-based tenant resolvers can pick the wrong tenant. With STRICT_MODE=False, this can disclose data across tenants. Upgrade to djust 1.0.7; no workaround other than upgrading is given.
