CVE-2026-65590

MEDIUMPre-NVD 5.55.5
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 5.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
