CVE-2025-59905Network attack vector

Client-side script execution via reflected procedure parameters

Published Feb 16, 2026 · Updated Feb 16, 2026

Reflected XSS in Kubysoft allows remote authenticated users to run arbitrary client-side scripts through a crafted endpoint request. The /node/kudaby/nodeFN/procedure endpoint reflects multiple request parameters into its HTTP response without adequate neutralization, causing the victim's browser to execute them. A low-privileged attacker must induce active victim interaction; execution is confined to the browser context and affects confidentiality and integrity without interrupting service.
