AI-suggested
Until a fix is provided, restricting network access to device management interfaces and using network-level controls may reduce exposure, but these are not full mitigations for the hardcoded credential issue.
Description
Yarbo firmware v2.3.9 contains hardcoded administrative credentials embedded in the firmware image. These credentials are identical across all devices running this firmware and cannot be changed or removed by end users, enabling trivial unauthorized access to device management interfaces by anyone who knows them.
