Codecanyon Tiva Events Calender cross site scripting

The vulnerability is triggered by manipulating the 'name' argument during a POST request to the `/admin/report/edit.php` endpoint. An attacker can inject malicious script into this argument, which is then reflected in the application's response. The attack can be initiated remotely, and the exploit has been publicly disclosed [ref_id=1].

The advisory suggests several remediation steps to address the vulnerability. These include encoding and escaping the content of the 'name' input field before transmission, restricting the input field to disallow special characters, and sanitizing output locations on both the frontend and backend by encoding them to prevent script execution [ref_id=1].

The public exploit reference provides a link to a full disclosure which includes PoC session logs detailing the manipulation of the 'name' argument and the resulting HTTP requests and responses [ref_id=1].
