The vulnerability CVE-2024-56267 affects the html5maps Interactive UK Map product up to version 3.4.8. It is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that persist on the affected application and execute in the context of users' browsers when they access the compromised content. The CVSS v3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this stored XSS vulnerability can lead to execution of arbitrary scripts in users' browsers, potentially resulting in theft of sensitive information, session hijacking, or disruption of application availability. The CVSS score reflects partial impacts on confidentiality, integrity, and availability. There are no known exploits in the wild currently.

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. Monitoring for suspicious activity related to this vulnerability is recommended. Avoid using affected versions of the Interactive UK Map if feasible.
