CVE-2026-1871
Last modified
CVE-2026-1871 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. TP-Link Tapo C200 v5 contains a stack-based buffer overflow flaw in RTSP authentication handling due to improper validation of Authorization header field lengths, which can be triggered by a crafted authentication request. Successful exploitation causes the affected RTSP core service process to crash and triggers an automatic system reboot, resulting in a denial of service (DoS) condition. This prevents legitimate users from accessing the camera’s live video stream or management interface until the service restarts.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
