CVE-2026-0853 is classified as a medium severity vulnerability affecting certain Network Video Recorder (NVR) models developed by A-Plus Video Technologies. This vulnerability allows unauthenticated remote attackers to access the debug page, exposing sensitive device status information. With a CVSS score of 6.9, it poses a moderate level of risk, warranting immediate attention from security teams.
Risk to organizations includes unauthorized access to sensitive information, which could lead to further exploitation or compromise of the affected devices. Although there are currently no known exploits for this vulnerability, organizations should not underestimate the potential for attackers to develop methods to exploit it.
Organizations should prioritize patching immediately to mitigate this risk. Given the accessibility of the debug page and the nature of the vulnerability, it is crucial to address this issue in compliance with security best practices.
As of now, the vulnerability remains in a deferred status, which indicates that it may not yet be actively exploited. However, continuous monitoring is advised to remain alert for any developments related to this vulnerability.
Vulnerability Details
The vulnerability identified by CVE-2026-0853 allows attackers to exploit sensitive data exposure in certain NVR models from A-Plus Video Technologies. The official description states that this vulnerability permits unauthenticated remote attackers to access the debug page, thereby obtaining device status information.
The CVSS score for this vulnerability is 6.9, categorized as medium severity. It is classified under CWE-497, which pertains to exposure of sensitive information through the use of a debug page. This vulnerability was published on January 12, 2026, and the last modification occurred on April 15, 2026.
Technical Analysis
The root cause of CVE-2026-0853 is the failure to properly secure sensitive data exposed on the debug page of the affected NVR models. The attack vector is network-based, with low complexity involved in the exploitation, meaning that no special skills are required to access the debug page.
Attackers do not require any privileges or user interaction to exploit this vulnerability. The impact on confidentiality is low, as it only allows access to device status information without compromising integrity or availability.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-0853 involves potential unauthorized access to device configurations and status, which could lead to greater exposure of sensitive information or further exploitation of the system. The urgency for organizations to address this vulnerability is underscored by its medium CVSS score, which indicates that while immediate exploitation may not be occurring, the potential for future attacks exists.
Organizations operating affected NVR models should prioritize remediation efforts based on their risk management strategies. Implementing network controls and monitoring can help mitigate the exposure until a patch is applied.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
Currently, specific version details for affected NVR models are not disclosed. Organizations should assume that all versions prior to the vendor patch may be vulnerable.
Mitigation & Remediation
