CVE-2026-102369 · Severity: info · Published 2026-10-01

TP-Link Tapo indoor/outdoor security cameras (C120 v1 and C200 V5) contain multiple security flaws in their authentication and input validation mechanisms. An attacker on the same local network can replay login challenge data to gain administrative access, activate a hidden privileged service, and execute arbitrary commands on the camera device, potentially compromising video feeds, snapshots, and device integrity.
