A stored cross-site scripting (XSS) vulnerability exists in certain 1xxx series NVR devices due to insufficient sanitization of user-supplied input in specific functional modules. Attackers can inject malicious scripts, which are then persistently stored on the device backend. When administrators or users access affected pages, the stored scripts are executed in their browsers, leading to potential session hijacking, unauthorized actions, or data theft.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
