Deeper analysis

CVE-2026-0855 is an OS Command Injection vulnerability (CWE-78) affecting certain IP camera models developed by Merit LILIN. Published on 2026-01-12, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact across confidentiality, integrity, and availability.

The vulnerability enables authenticated remote attackers with low privileges to inject and execute arbitrary OS commands on the affected device. Exploitation requires network access and low attack complexity but no user interaction, allowing attackers to achieve high-impact outcomes such as full device compromise, data exfiltration, or disruption of camera operations.
