CVE-2024-8622Network attack vector

Reflected XSS via unvalidated preview parameter

Published Sep 12, 2024 · Updated Apr 8, 2026

Reflected XSS in amCharts: Charts and Maps 1.4.4 and earlier allows remote attackers to execute script via a crafted preview request. The preview handler accepts the amcharts_javascript parameter as arbitrary JavaScript without nonce validation and reflects it into the rendered page. Exploitation requires no account, but a victim must follow a crafted link or perform an equivalent attacker-directed action; the script then runs in that victim's browser context.
