CVE-2026-0853Network attack vector

Unauthenticated device-status disclosure via exposed debug page

Published Jan 12, 2026 · Updated Jan 12, 2026

Information disclosure in A-Plus Video NVR firmware 2.1.0 and earlier allows remote attackers to read device status via a debug page. The web interface serves the diagnostic page and its device-status output without enforcing authentication; no public source identifies the page path or handler. Network access to the NVR is sufficient, and the documented consequence is limited to disclosure of device status rather than configuration changes or service interruption.
