This vulnerability involves a Cross Site Scripting (XSS) flaw in Apartment Visitors Management System V1.1. An authenticated attacker can inject arbitrary JavaScript code via the visname parameter in visitors-form.php. The injected script is executed when the input is rendered in manage-newvisitors.php or visitor-detail.php, potentially allowing script execution in the context of a logged-in user. There is no CVSS score or vendor advisory available, and no patch or remediation information has been provided.

Successful exploitation allows an authenticated attacker to execute arbitrary JavaScript in the context of other authenticated users viewing the affected pages. This could lead to session hijacking, unauthorized actions, or other client-side attacks. However, exploitation requires authentication, which limits the attack surface. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to authenticated users and consider additional input validation or output encoding controls on the visname parameter to mitigate injection risks.
