Vulnerability from github – Published: 2026-08-19 21:30 – Updated: 2026-09-04 18:31

Details

Tapo C100/C101 V5 contains a null pointer dereference vulnerability in the RTSP service. An attacker on the local network can send specially crafted requests that cause the service to dereference an invalid pointer, resulting in a service crash and device reboot. Successful exploitation can disrupt live video streaming functionality and cause a temporary denial-of-service condition.

Severity

6.5 (Medium)
