This vulnerability in Rometheme RTMKit involves improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). Attackers can inject malicious scripts that persist on the affected web pages, potentially impacting users who visit those pages. The issue affects all versions up to 1.6.0. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with scope changed and low impacts on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, session hijacking, or other impacts on user data and application integrity. The CVSS score of 6.5 reflects a medium severity with partial impact on confidentiality, integrity, and availability. There are no known exploits in the wild at this time.

No official patch or remediation guidance is currently available from the vendor. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, users should consider limiting exposure by restricting access to affected versions and applying web application firewall (WAF) rules to detect and block XSS payloads where possible.
