CVE-2026-105808: Cross Site Scripting in SourceCodester Simple Student Information System

CVE-2026-105808 is a cross-site scripting vulnerability in SourceCodester Simple Student Information System 1.0. The flaw exists in the clean function of the searchresults.php file, where insufficient sanitization of the searchbox parameter allows remote attackers to inject and execute arbitrary scripts. This vulnerability can be triggered remotely without authentication. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, partial user interaction, and limited impact on confidentiality and integrity.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to session hijacking, defacement, or redirection to malicious sites. However, the impact is limited as indicated by the medium severity score and partial user interaction requirement.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying input validation or sanitization controls on the searchbox parameter to mitigate exploitation risk.
