## Technical details

The GET /api/v1/messages/conversation/:id endpoint in Trudesk lacks participant validation, allowing any authenticated attacker to retrieve conversations by guessing or enumerating conversation IDs. The vulnerability exposes full message history along with participants' usernames, full names, and email addresses without checking if the requester is a legitimate participant. This is a horizontal privilege escalation requiring only valid authentication credentials.
