Expense Tracker 1.0 – ‘Expense Name’ Stored Cross-Site Scripting

This vulnerability allows an attacker to inject malicious payloads in the Expense Category section and paste the payload in the desired field. Each time the admin or user visits and manages the user data, the malicious payload (XSS) triggers, allowing the attacker to capture the admin cookies and access the users' data in plain text.

Mitigation:

To mitigate this vulnerability, the application should properly validate and sanitize user inputs before displaying them on the website. It is recommended to use output encoding or escaping techniques to prevent the execution of malicious scripts.
