Input validation vulnerability in Jeeng Push Notifications 2.0.3

The Jeeng Push Notifications plugin for WordPress is not secure in versions up to 2.0.3. This means that attackers who do not have permission to make changes to the plugin’s settings can still do so by tricking a site administrator into clicking on a malicious link. This is because the jeeng_page() function does not have any checks in place to make sure the request is legitimate.
