CVE-2025-11960Network attack vector

Browser script execution via undisclosed reflected input

Published Nov 11, 2025 · Updated Nov 11, 2025

Reflected XSS in Aryom KVKNET before 2.1.8 allows remote attackers to execute script in a user's browser through a crafted request. The CNA and government advisory do not identify the affected request parameter or the output path that returns it without sufficient neutralization. Exploitation is unauthenticated but requires a user to interact with attacker-controlled content; reported effects are limited to reading or changing data in the browser's security context, with no service interruption.
