Description
Trudesk through 1.2.11 contains an authorization bypass vulnerability that allows any authenticated user to read private conversations by supplying another conversation's id. Attackers can request GET /api/v1/messages/conversation/:id, which lacks participant checks, to obtain full message history plus participants' usernames, full names and email addresses.
