WuzAPI through 1.1.0 contains a cross-tenant information disclosure vulnerability in the GetHistory handler that allows authenticated users to view other tenants' chat metadata. Attackers with message history enabled can request GET /chat/history with chat_jid=index to list every user's internal ID, stored chat JIDs, and last-message times.
