CVE-2026-24751Network attack vector

Browser script execution via reflected input

Published Jun 1, 2026 · Updated Jun 1, 2026

Reflected XSS in Kiteworks Secure Data Forms before 9.3.0 allows remote attackers to execute arbitrary JavaScript in a user's browser. The vendor identifies an obsolete Secure Data Forms component but has not disclosed the affected endpoint, parameter, or missing output-neutralization step. Exploitation requires no account but does require a user to follow an attacker-controlled request; resulting script execution can expose browser-accessible data and alter page content.
