CVE-2025-13894Network attack vector

Browser script execution via unescaped PHP_SELF output

Published Dec 6, 2025 · Updated Apr 8, 2026

Reflected XSS in SumoTTo CSV Sumotto 1.0 and earlier allows remote attackers to inject browser scripts through crafted request paths. The csv_sumotto_settings.php code outputs the request-controlled PHP_SELF value into the generated page without sanitization or output escaping. Exploitation requires no account but requires a user to follow an attacker-controlled link, after which the script runs in that user's browser context.
