Summary

Duplicate Advisory: computer-use Shell Sandbox Not Enforced on Linux and Windows

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-fpg6-x68q-5793. This link is maintained to preserve external references.

Original Description

n8n before 2.29.8 and 2.30.x before 2.30.1 does not enforce shell sandbox restrictions on Linux and Windows in the @n8n/computer-use package (sandboxing was applied only on macOS). Shell commands executed by the tool run without any filesystem or network restrictions, allowing unrestricted access to the host filesystem and network from within the computer-use agent process. This issue only affects deployments where the @n8n/computer-use package is explicitly installed and running; standard n8n installations are not affected.

Severity

5.5 (Medium)
