The vulnerability CVE-2025-22310 affects marsian TemplatesNext ToolKit versions up to 3.2.9 and involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). This allows attackers to inject malicious scripts that persist on the affected web pages, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and partial impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, modification of data, or disruption of service. The impact is rated medium based on the CVSS score of 6.5, reflecting limited but meaningful confidentiality, integrity, and availability impacts.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users of TemplatesNext ToolKit should monitor the vendor's communications for updates.
