CVE-2026-65590Network attack vector

Authenticated host access via unenforced shell sandbox

Published Jul 22, 2026 · Updated Jul 22, 2026

Sandbox bypass in n8n before 2.29.8 and 2.30.x before 2.30.1 allows remote authenticated users to access host files and networks. The @n8n/computer-use shell tool applies sandbox restrictions only on macOS, leaving Linux and Windows commands unrestricted. Exploitation requires high-privilege access and an explicitly installed, running computer-use package; standard n8n deployments are unaffected.
