CVE-2024-9864Network attack vector

Stored XSS via unescaped ticket names

Published Oct 24, 2024 · Updated Apr 8, 2026

Stored XSS in EventPrime 4.0.4.7 and earlier allows remote attackers to inject scripts through ticket names in front-end events. The front-end event-submission path stores ticket-name input without sufficient sanitization, and affected views render it without context-appropriate escaping. Exploitation requires front-end event submission with tickets to be enabled and a user to open the injected page, where the script runs in that user's browser.
