A stored cross-site scripting vulnerability has been identified in PHPGurukul Daily Expense Tracker System version 1.1. The issue arises from the file '/dets/includes/sidebar.php', where user-supplied data, specifically the 'FullName' attribute, is processed without proper output encoding. This flaw allows for the injection of JavaScript, which is executed in the browsers of users who view the affected pages. The vulnerability can be exploited remotely.
Users are advised to apply proper output encoding to all user-supplied data before rendering it in HTML. Implementing Content Security Policy headers and setting HttpOnly and Secure flags on session cookies can also help mitigate the risk.
