CVE-2025-13795 identifies a cross-site scripting (XSS) vulnerability in the codingWithElias School Management System, affecting the Edit Student Info Page located in /student-view.php. The vulnerability stems from insufficient input validation and sanitization of the 'First Name' parameter, which allows an attacker to inject malicious JavaScript code. This flaw can be exploited remotely by manipulating the input fields, potentially leading to the execution of arbitrary scripts in the context of the victim's browser. The vulnerability requires the attacker to have privileges to edit student information, implying some level of authenticated access, and user interaction is necessary for the payload to execute. The CVSS 4.0 score is 4.8 (medium severity), reflecting the moderate impact and exploitation complexity. The product follows a rolling release model, complicating version tracking and patching. The vendor has not responded to the vulnerability disclosure, and no official patches or updates have been released. Although no known exploits are currently active in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. This vulnerability could be leveraged to steal session cookies, perform phishing attacks, or deface the user interface, impacting confidentiality and integrity of user data within the school management system.

For European organizations, particularly educational institutions using the codingWithElias School Management System, this vulnerability poses risks to the confidentiality and integrity of student and staff data. Successful exploitation could allow attackers to execute malicious scripts, potentially leading to session hijacking, unauthorized data access, or manipulation of displayed information. This could result in data breaches, loss of trust, and compliance violations under regulations such as GDPR. The medium severity rating indicates that while the vulnerability is not critical, it can still be leveraged for targeted attacks, especially in environments where multiple users have editing privileges. The lack of vendor response and patches increases exposure time, raising the risk of exploitation. Additionally, the rolling release nature of the product complicates timely detection and remediation. European schools and educational bodies could face reputational damage and operational disruptions if attackers exploit this vulnerability to spread malware or conduct phishing campaigns within their networks.

To mitigate this vulnerability, organizations should implement strict input validation and sanitization on all user-supplied data, especially the 'First Name' field and other potentially affected parameters. Employing context-aware output encoding (e.g., HTML entity encoding) before rendering user inputs can prevent script execution. Restrict editing privileges to trusted users and enforce the principle of least privilege to limit potential attackers' access. Implement Content Security Policy (CSP) headers to reduce the impact of XSS attacks by restricting the sources of executable scripts. Regularly monitor application logs for suspicious input patterns or unusual user activity. Since no official patches are available, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting this endpoint. Engage in proactive vulnerability scanning and penetration testing to identify similar weaknesses. Finally, maintain communication channels with the vendor or community to receive updates or unofficial patches promptly.
