CVE-2024-56210Network attack vector

Victim-browser script execution via undisclosed reflection

Published Dec 31, 2024 · Updated Apr 28, 2026

Reflected XSS in DeluxeThemes UserPro 5.1.9 and earlier allows remote attackers to execute script in a victim's browser. Patchstack and the CNA record do not disclose the affected endpoint, parameter, or code path, only that untrusted input is reflected into generated page content without adequate neutralization. Exploitation requires a victim to open crafted content; the resulting script runs in the affected site's browser context and can access data or perform permitted actions.
