Missing Authentication for Critical Function
An issue was discovered in the Infosysta "In-App & Desktop Notifications" app 1.6.13_J8 for Jira. By using plugins/servlet/nfj/PushNotification?username= with a modified username, a different user's notifications can be read without authentication/authorization. These notifications are then no longer displayed to the normal user.
CWE-306 - Missing Authentication for Critical Function
The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
