CVE-2026-75969Network attack vector

Unauthenticated firmware installation via unchecked update authorization

Published Sep 30, 2026 · Updated Sep 30, 2026

Missing authentication in PTZOptics camera and Upgrade Tool firmware update modules allows remote attackers to install modified camera firmware. The firmware update path accepts an attacker-supplied image without checking administrator authorization before installation; the public record does not identify a specific endpoint or handler. The attacker needs network reachability to an affected camera, and a successful upload replaces device firmware rather than merely changing a setting.
