CVE-2026-2897Public exploitNetwork attack vector

Browser script execution via unescaped configuration values

Published Feb 22, 2026 · Updated Feb 22, 2026

Cross-site scripting in FunAdmin 7.1.0-rc1 through 7.1.0-rc4 allows remote authenticated users to execute script in backend users' browsers. The backend index template inserts system configuration values into HTML attributes and JavaScript without output escaping. High-privilege access is required to plant the value, and a backend user must load the affected page, enabling content modification in that browser context.
