The libcurl CURLOPTSSLVERIFYPEER option was disabled on a subset of requests made by Nest production devices which enabled a potential man-in-the-middle attack on requests to Google cloud services by any host the traffic was routed through.

An attacker in the wifi vicinity of a target Google Home can spy on the victim, resulting in Elevation of Privilege

There exists an authentication bypass vulnerability in OpenThread border router devices and implementations. This issue allows unauthenticated nodes to craft radio frames using “Key ID Mode 2”: a special mode using a static encryption key to bypass security checks, resulting in arbitrary IP packets being allowed on the Thread network. This provides a pathway for an attacker to send/receive arbitrary IPv6 packets to devices on the LAN, potentially exploiting them if they lack additional authentication or contain any network vulnerabilities that would normally be mitigated by the home router’s NAT firewall. Effected devices have been mitigated through an automatic update beyond the affected range.

An exploitable information disclosure vulnerability exists in the Weave PASE pairing functionality of the Nest Cam IQ Indoor, version 4620002. A set of specially crafted weave packets can brute force a pairing code, resulting in greater Weave access and potentially full device control. An attacker can send specially crafted packets to trigger this vulnerability.
