CVE-2026-3349Network attack vector

Browser script execution via unescaped redirect URL

Published May 27, 2026 · Updated May 27, 2026

Reflected XSS in MinhNhut Link Gateway 3.6.1 and earlier allows remote attackers to inject scripts through the redirect-page url parameter. The redirect handler passes the attacker-controlled value to templates/default/index.php, which emits it into HTML without sufficient sanitization or output escaping. Exploitation requires a user to follow a crafted link; the script then executes in that user's browser under the affected site's origin.
