CVE-2026-36214Public exploitNetwork attack vector

Staff session compromise via tooltip template injection

Published Jul 14, 2026 · Updated Jul 14, 2026

Stored XSS in osTicket 1.10 through 1.17.7 and 1.18.0 through 1.18.3 allows remote attackers to run JavaScript in staff sessions. The safe_html sanitizer permits attacker-controlled data-* attributes, and Bootstrap Tooltip 3.3.4 inserts data-template as HTML into the DOM. A ticket submitter must store crafted content and an Agent or Admin must view it; the script then acts with that staff member's privileges.
