CVE-2025-23599Network attack vector

Browser-context script execution

Published Feb 3, 2025 · Updated May 11, 2026

Reflected XSS in Aarvansh Infotech eMarksheet 5.4.3 and earlier allows remote attackers to execute scripts through crafted links. Public advisories attribute the flaw to insufficient input sanitization and output escaping but do not disclose the affected parameter, handler, or template. Exploitation requires a user to follow an attacker-controlled link; injected script then runs in the browser context and can read or modify data available to the page.
