This vulnerability (CVE-2026-65470) is classified as CWE-79, indicating improper neutralization of input leading to cross-site scripting (XSS) in Fluent Support versions up to and including 2.3.0. The issue allows users with contributor privileges to inject malicious scripts during web page generation. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges at the contributor level, user interaction required, and impacts on confidentiality, integrity, and availability at low to partial levels. No vendor advisory or patch information is currently available, and the product is not a cloud service.

Successful exploitation could allow an attacker with contributor-level access to execute arbitrary scripts in the context of the affected application, potentially leading to partial compromise of confidentiality, integrity, and availability of the system. This may result in unauthorized actions performed on behalf of users or data exposure within the application environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit contributor-level access where possible and monitor for suspicious activity related to script injection. Avoid relying on generic mitigations as the vendor has not provided specific guidance.
