This vulnerability (CVE-2025-11963) involves improper input sanitization in StarCities before version 1.1.61, leading to reflected Cross-site Scripting (CWE-79). An attacker could craft malicious input that is reflected in web pages without proper neutralization, potentially executing arbitrary scripts in users' browsers. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requires low privileges and user interaction, with a scope change and limited confidentiality and integrity impact but no availability impact.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to information disclosure or session hijacking. The impact is limited to confidentiality and integrity with no direct availability impact. No known active exploitation has 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 standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor channels for updates regarding patches or official mitigations.
