Descripción

*** Pendiente de traducción *** Supabase Realtime provides Broadcast, Presence, and Postgres Changes via WebSockets. Prior to 2.111.2, Realtime authorization does not correctly honor the per-extension presence.read row-level security policy when a private-channel client is allowed presence.write but explicitly denied presence.read. Under that differential policy, the client can receive presence_diff messages containing other members' presence metadata, including application-defined location, online-status, roster, viewing, or typing information. Deployments with uniform presence visibility have no differential, and postgres_changes row data is unaffected. This issue is fixed in version 2.111.2.
