Executive Summary

CVE-2026-0547 is a critical vulnerability in PHPGurukul Online Course Registration up to version 3.1, specifically in the student registration photo upload feature (/admin/edit-student-profile.php). The application does not properly validate or sanitize uploaded files, allowing attackers to upload malicious SVG or HTML files containing embedded JavaScript. When an administrator views or edits a student profile with such a malicious file, the embedded script executes in their browser, potentially leading to session cookie theft, unauthorized administrative actions, or redirection to phishing sites. [1, 3]

Impact Analysis

This vulnerability can impact you by allowing attackers to execute malicious scripts in the context of an administrator's browser. This can lead to theft of session cookies, unauthorized actions performed with administrative privileges, and redirection to phishing sites. It compromises the confidentiality, integrity, and availability of the system and can be exploited remotely with minimal authentication. [1, 3]

Detection Guidance

This vulnerability can be detected by checking for the presence of the vulnerable endpoint /admin/edit-student-profile.php and monitoring for uploads of malicious files via the photo argument. Attackers may use Google dorking with the query inurl:admin/edit-student-profile.php to identify vulnerable targets. To detect exploitation attempts on your system, you can monitor web server logs for POST requests to /admin/edit-student-profile.php containing file uploads, especially SVG or HTML files. Example commands include using grep on access logs: grep '/admin/edit-student-profile.php' /var/log/apache2/access.log and inspecting uploaded file types in the application upload directory. Additionally, monitoring for unusual file types or scripts in the upload folder can help detect exploitation attempts. [3]

Mitigation Strategies

Immediate mitigation steps include restricting or disabling file uploads via the photo argument in /admin/edit-student-profile.php, implementing strict server-side validation to allow only safe image file types, and sanitizing uploaded files to prevent embedded scripts. Since no known countermeasures or mitigations have been reported, it is recommended to limit access to the vulnerable page to trusted administrators only, monitor for suspicious activity, and apply any available patches or updates from the vendor once released. Additionally, consider implementing web application firewall (WAF) rules to block malicious file uploads and cross-site scripting attempts. [3]
