More than 1,500 of such users were able to enlarge the thumbnails from which other homes could be viewed, according to Wyze, which noted that the issue has been caused by a newly integrated "third-party caching client system." "This client library received unprecedented load conditions caused by devices coming back online all at once. As a result of increased demand, it mixed up device ID and user ID mapping and connected some data to incorrect accounts," said Wyze. While more than 99% of its users were not affected by the incident, Wyze expressed its commitment to further bolster its security defenses.
