What is CVE-2026-65590?

CVE-2026-65590 is a medium-severity command injection vulnerability in N8n N8n, published on 22 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official 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.

Weakness: CWE-78
