CVE-2026-65590
Last modified
CVE-2026-65590 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
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.
