CVE-2026-20766

Description of the Vulnerability

CVE-2026-20766 is a critical vulnerability affecting specific firmware versions of Milesight AIOT cameras. The issue stems from an out-of-bounds memory access flaw, which allows attackers to exploit vulnerabilities in the camera's firmware to gain unauthorized access or disrupt operations.

The vulnerability has been rated with a CVSS score of 8.8 (HIGH), indicating severe potential for exploitation. This high score reflects the risk of remote exploitation, data compromise, and system disruption if not addressed promptly.

Affected Systems

The vulnerability impacts certain firmware versions of Milesight AIOT cameras. Specifically, affected devices are those running firmware version X.X.X (exact details depend on the vendor's release notes). Users should verify their camera firmware version against official documentation to confirm exposure.

Impact and Exploitability

The high CVSS score underscores the severity of this vulnerability. Attackers could exploit it to execute arbitrary code, leading to unauthorized control of the device or data exfiltration. The vulnerability is fully exploitable remotely, requiring no prior access to the system.

Due to the nature of IoT devices, a successful exploitation could compromise network security, allowing attackers to use the camera as a gateway to other connected systems.
