> Eufy Omni C20 and Omni X10 Pro robot vacuums below v1.6.4 carry command injection, hard-coded credential, and certificate validation flaws enabling remote code execution.

CISA published an ICS advisory detailing three vulnerabilities in Eufy's Omni C20 and Omni X10 Pro robot vacuum/cleaning devices, all fixed in firmware version 1.6.4. The most severe, CVE-2026-93289, is an unauthenticated command injection flaw (CWE-78) affecting both models that allows an attacker to execute system-level commands during the device pairing process. The Omni C20 alone is additionally affected by CVE-2026-93290, use of hard-coded credentials (CWE-798) that could let an attacker who can access log files obtain credentials granting access to sensitive data such as mapping information, and CVE-2026-93291, improper certificate validation (CWE-295) that could enable a man-in-the-middle attacker to execute arbitrary code.

The affected products are consumer/IoT devices manufactured by Eufy (headquartered in China) and deployed worldwide, falling under the Information Technology critical infrastructure sector. CISA states no known public exploitation of these vulnerabilities has been reported at this time. The vulnerabilities were responsibly disclosed to CISA by a researcher identified as Jared of Somerset Recon.

Remediation is straightforward: Eufy recommends all users upgrade affected Omni C20 and Omni X10 Pro devices to firmware version 1.6.4 or later. CISA additionally recommends standard network hygiene for control system devices — minimizing internet exposure, isolating device networks behind firewalls, and using VPNs for any required remote access, while noting VPNs themselves require ongoing patching and are only as secure as connected endpoints.
