CVE-2026-86148Network attack vector

Authenticated command execution via AlarmVoiceURL injection

Published Sep 5, 2026 · Updated Sep 8, 2026

OS command injection in Tenda CP3 27.5.57.101 allows remote authenticated users to execute commands through AlarmVoiceURL. The Kylin SystemAsh function in Apis/system.c incorporates the attacker-controlled AlarmVoiceURL value into an operating-system command without neutralizing command syntax. High-privilege authentication is required, and successful injection permits command execution on the network-connected camera.
