CVE-2025-49583Public exploitNetwork attack vector

Notification spam via unanalyzed email-renderer properties

Published Jun 13, 2025 · Updated Jun 13, 2025

Insufficient warning in affected XWiki Platform releases allows remote authenticated users to send deceptive notification emails. The required-rights analyzer omits XWiki.Notifications.Code.NotificationEmailRendererClass properties, so attacker-supplied templates are trusted when the document is resaved. Exploitation requires a low-privileged user to create the object and an administrator to edit and save it; the result is phishing spam or suppressed notifications, not code execution.
