CVE-2026-114392
MEDIUM 6.9Trudesk through 1.2.11 contains an authorization bypass vulnerability that allows authenticated users to read tickets outside their groups via GET /api/v1/tickets/:uid. Attackers can enumerate sequential ticket uids to read every ticket's subject, issue, comments, owner and assignee, because the apiTickets.single handler skips group membership checks.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
