This vulnerability in Ninja Team File Manager Pro (up to version 1.8.8) is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. An attacker with high privileges can inject malicious scripts that are stored and later executed when viewed by users with appropriate permissions. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with limited impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with high privileges to execute arbitrary scripts in the context of the affected application, potentially leading to limited disclosure or modification of data and limited disruption of service. The impact is rated medium with a CVSS score of 5.9. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected application to trusted users only and monitor for suspicious activity. Avoid executing untrusted input in the application context.
