The code-projects Employee Management System version 1.0 contains a cross-site scripting vulnerability in the /applyleave.php file. Specifically, improper handling of the ID parameter allows an attacker to inject malicious scripts that execute in the context of the victim's browser. This vulnerability is remotely exploitable without privileges and requires user interaction to trigger. The CVSS 4.0 base score is 5.3, indicating a medium severity level. No official fix or patch has been published by the vendor as of the current information.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a user's browser session, potentially leading to session hijacking, defacement, or other malicious actions within the affected web application. However, the attack requires user interaction and does not grant direct system access or privilege escalation.

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 output encoding on the ID parameter in /applyleave.php to mitigate XSS risks. Additionally, employing web application firewalls (WAFs) that detect and block XSS payloads may reduce exposure.
