CVE-2026-111345
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.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
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.
