Questions about CVE-2026-93291
What does this mean?
The device does not properly validate certificates, which could let an attacker perform a man-in-the-middle attack. The advisory says this could allow the attacker to execute arbitrary code.Source: cisa.gov
Am I affected, and how do I check?
Eufy Omni C20 firmware versions earlier than 1.4.6 are in the affected range. Compare your device's firmware version with 1.4.6 to see where it falls.Source: cisa.gov
What should I do about it?
Upgrade the Eufy Omni C20 to version 1.4.6 or later, which Eufy recommends.Source: cisa.gov
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
