This vulnerability affects code-projects Coaching Management System 1.0, specifically in the Complaint Form Page component located at /cims/modules/student/complaint.php. An attacker can remotely manipulate the Complaint argument to perform cross-site scripting (XSS) attacks. The CVSS 4.0 base score is 5.1, indicating medium severity, with network attack vector, low attack complexity, no privileges required, and user interaction required. The vulnerability was published on April 28, 2026, and no official remediation or patch has been documented.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application for users interacting with the Complaint Form Page. This may lead to session hijacking, defacement, or other client-side impacts typical of XSS vulnerabilities. However, there is no evidence of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, users should monitor for vendor updates. Until a patch is available, consider applying input validation or output encoding on the Complaint argument as a temporary mitigation if possible.
