Recommendation: Plan a near-term fix — a public PoC already exists.

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.
