CVE-2026-3402 Details
Description
A security vulnerability has been detected in PHPGurukul Student Record Management System up to 1.0. This vulnerability affects unknown code of the file /edit-course.php. Such manipulation of the argument Course Short Name leads to cross site scripting. The attack can be executed remotely. The exploit has been disclosed publicly and may be used.
A stored cross-site scripting vulnerability has been identified in PHPGurukul Student Record Management System versions through 1.0. The issue resides in the /edit-course.php file, specifically within the Course Short Name field. The vulnerability allows authenticated administrators to inject malicious JavaScript, which is then executed when the course is viewed or edited. This exploitation occurs due to improper input validation and output encoding, allowing injected scripts to be executed in the context of the user’s session.
To address this vulnerability, implement strict server-side input validation and sanitization for the Course Short Name field. Ensure that all user-supplied output is encoded using context-aware encoding methods, such as htmlspecialchars() in PHP, before being rendered in the browser. Additionally, consider applying a strong Content Security Policy (CSP) to mitigate the impact of any potential script injection.
