Administrator-level stored script execution
Published May 8, 2023 · Updated Apr 28, 2026
Stored XSS in CoreFortress Easy Event Calendar 1.0 and earlier allows remote authenticated users to inject scripts into generated pages. Public records do not identify the affected input field, handler, or rendering path; they establish only that content is stored and rendered without adequate neutralization. Administrator-level access is required to plant a payload, and a visitor must open the affected page before the script runs in that visitor's browser session.
