CVE-2026-6281Network attack vector

Authenticated command execution via undisclosed injection point

Published May 13, 2026 · Updated May 13, 2026

OS command injection in Lenovo Personal Cloud Storage firmware allows remote authenticated users on the local network to execute arbitrary commands. Lenovo has not published the affected interface, parameter, or command-construction path that fails to neutralize untrusted input. A valid device account and local-network reachability are required; successful exploitation grants command execution on the storage appliance.
