Attackers can lure users running the Local Gateway into opening a crafted n8n-computer-use:// link to connect their computer to an attacker-controlled instance, inheriting previously granted permissions and acting on the computer through the gateway.","epss":{"date":"2026-11-02","percentile":0.05668,"score":0.00165},"exploits":[],"kev":null,"metrics":[{"score":5.9,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},{"score":5.9,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","version":"3.1"}],"modifiedAt":1793712013014,"publishedAt":1793213989747,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-cwm2-vhf5-27q9"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/n8n-before-2.41.4-and-2.42.1-local-gateway-deep-link-silent-re-pairing-to-attacker-instance"}],"remediation":[],"revision":"081f2ea2104347bbceb88ad00a5f30329e5b9ffcd08a5b6118ba85dd8f35eb77","sources":[{"modifiedAt":1793712013014,"name":"CNA: VulnCheck","retrievedAt":1793714957369,"url":"https://www.cve.org/CVERecord?id=CVE-2026-118677"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793714963534,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-118677"}],"ssvc":{"assessedAt":1793711997149,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"n8n before 2.41.4 and 2.42.1 Local Gateway Deep-Link Silent Re-pairing to Attacker Instance","updatedAt":1793714963534}
