Ubiquiti has issued emergency patches for five critical and high-severity UniFi OS vulnerabilities (including multiple CVSS 10.0 flaws) that enable unauthenticated remote command injection, path traversal, and improper access control across dozens of UniFi devices; administrators should immediately apply the specified firmware versions, restrict management access, and review audit logs.
