CVE-2025-26543Network attack vector

Stored XSS via forged settings update

Published Feb 13, 2025 · Updated Apr 28, 2026

CSRF in Pukhraj Suthar Simple Responsive Menu 2.1 and earlier allows remote attackers to store XSS payloads through forged settings updates. The settings-update function accepts forged requests because nonce validation is missing or incorrect; public sources do not name the function or affected parameter. Exploitation requires a site administrator to perform an attacker-induced action, after which stored scripts execute in visitors’ browser sessions and can alter displayed content or access session-visible data.
