CVE-2026-44956Network attack vector

Administrator-session script execution via unescaped email logs

Published Jun 23, 2026 · Updated Jun 23, 2026

Stored XSS in Revive Adserver 6.0.6 and earlier allows remote authenticated users to execute JavaScript in an administrator's browser. The Full Name value is copied into system-generated email content stored in the userlog table, and userlog-details.php renders that content without output escaping. A low-privilege account must plant the payload and an administrator must view the affected email log; execution is confined to the administrator's browser context.
