CVE-2026-111345
MediumCVSS 4.3Summary
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.
Risk Assessment
Authenticated users can read others' private conversations, leading to communication confidentiality breaches and exposure of personal data.
Recommendation
Update Trudesk to a version later than 1.2.11 if available, or implement participant checks in the GET /api/v1/messages/conversation/:id endpoint.
