CVE-2025-13950Network attack vectorHinoki check available

Unauthenticated settings modification via unchecked POST requests

Published Dec 15, 2025 · Updated Dec 15, 2025

Missing authorization in OneSignal – Web Push Notifications 3.6.1 and earlier allows remote attackers to alter settings via POST requests. The settings-save path in v3/onesignal-admin/onesignal-admin.php writes submitted App ID, REST API key, and notification options without checking a nonce or the manage_options capability. No WordPress account is required, and attackers can replace OneSignal credentials and change automatic notification behavior.
