This vulnerability in eZee Online Hotel Booking Engine involves improper sanitization of user input during web page generation, leading to stored cross-site scripting (XSS). Attackers could inject malicious scripts that are stored by the application and executed when other users view the affected pages. The vulnerability affects all versions up to 1.0.0. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to execute malicious scripts in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. This could result in session hijacking, defacement, or other malicious actions within the affected application environment. However, no known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should apply strict input validation and output encoding as a temporary mitigation. Monitor vendor communications for updates on patches or official mitigations.
