CVE-2023-34840Public exploitNetwork attack vector

Browser script execution via unsanitized notification message

Published Jun 30, 2023 · Updated Jul 9, 2026

Cross-site scripting in angular-ui-notification 0.1.0 through 0.3.6 allows remote attackers to execute script in a user's browser. The Notification service places the user-controlled message value into an ng-bind-html notification template without sanitizing or encoding it. Exploitation requires a consuming application to pass attacker-controlled content to message and a user to render the notification; script execution can read or alter data available to that page.
