Yi Technology's YI Home Camera 2 firmware 2.1.1_20171024151200 was found to contain two high-severity vulnerabilities in home/web/ipc, including hard-coded credentials tracked as CVE-2026-4475 and improper cryptographic signature verification in the HTTP firmware update handler tracked as CVE-2026-4478. The hard-coded credentials issue could allow an attacker with local network access to compromise the device, while the firmware update flaw could enable remote abuse of the update mechanism despite higher attack complexity.
Both issues were publicly disclosed with reports indicating exploit details are available, increasing the risk of real-world abuse against affected cameras. The vulnerabilities are classified under CWE-798/CWE-259 for embedded credentials and CWE-345/CWE-347 for signature verification failures, and the vendor reportedly did not respond after being contacted before disclosure.
