This vulnerability in fbtemplates Nemesis All-in-One (versions up to 1.1.3) involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). An attacker could inject malicious scripts that persist on the server and execute in the context of users' browsers, potentially leading to limited confidentiality, integrity, and availability impacts as reflected by the CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L). No patch or official remediation guidance is currently documented.

Successful exploitation could allow an attacker with low privileges and requiring user interaction to execute malicious scripts in the context of other users, potentially leading to limited information disclosure, modification, or disruption of service. The vulnerability affects confidentiality, integrity, and availability to a limited extent as per the CVSS score of 6.5.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor channels for updates and apply official fixes once released.
