CVE-2025-28357Public exploitNetwork attack vector

Reflected XSS via unsanitized URL paths

Published Oct 1, 2025 · Updated Jul 5, 2026

CRLF injection in Neto CMS 6.313.0 through 6.314.0 allows remote attackers to execute script in a victim's browser via a crafted URL. For invalid or nonexistent resources, path and cookie-storage logic fails to sanitize encoded CRLF bytes before placing the path in response headers, permitting header and body injection. A victim must open the URL; the reflected XSS can expose session data or perform actions within that victim's authenticated browser context.
