Improper access control in the HTTP server in YI Car Dashcam v3.88 allows unrestricted file downloads, uploads, and API commands. API commands can also be made to make unauthorized modifications to the device settings, such as disabling recording, disabling sounds, factory reset.

A vulnerability exists in the daemon process of the Yi IOT XY-3820 v6.0.24.10, which exposes a TCP service on port 6789. This service lacks proper input validation, allowing attackers to execute arbitrary scripts present on the device by sending specially crafted TCP requests using directory traversal techniques.

The YI Smart Kami Vision com.kamivision.yismart application through 1.0.020231219 for Android allows a remote attacker to execute arbitrary JavaScript code via an implicit intent to the com.ants360.yicamera.activity.WebViewActivity component.
