CVE-2025-44148Public exploitNetwork attack vector

Script execution via reflected failure.aspx input

Published Jun 3, 2025 · Updated Jul 5, 2026

Reflected XSS in MailEnable Webmail 10.53 and earlier allows remote attackers to execute script through a crafted failure.aspx link. The failure.aspx component reflects the attacker-controlled state query value into the response without neutralizing JavaScript syntax. Exploitation requires a logged-in user to follow the crafted link, after which the script runs in that user's browser session.
