CVE-2026-63081Network attack vector

Authenticated stored XSS via ticket Notes field

Published Jul 16, 2026 · Updated Jul 16, 2026

Stored XSS in Ultimate Fosters Perfect Support Ticketing & Document Management System through 1.7 allows remote authenticated users to run scripts. The ticket Notes field stores Agent-supplied payloads without neutralizing executable markup, then renders them in the browsers of users who view the assigned ticket. Agent-level access and a victim viewing the notes are required; execution in a Superadmin browser can expose its session or perform unauthorized actions in that session.
