CVE-2026-14871Public exploitNetwork attack vector

Cross-department data disclosure via missing ticket permission check

Published Jul 17, 2026 · Updated Jul 17, 2026

Incorrect authorization in osTicket 1.17.7 and 1.18.3 allows remote authenticated users to read ticket fields across departments. The viewField() method in include/ajax.tickets.php resolves attacker-supplied ticket and field identifiers but omits the parent ticket checkStaffPerm() authorization check. A low-privileged agent account and guessable identifiers are sufficient to retrieve restricted field data from another department.
