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.","categories":["Frameworks"],"product":"n8n","vendor":"n8n-io","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118677","source_modified_at":"2026-10-28T18:59:49.747Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":"n8n","vendor":"n8n-io","versions":[{"version":"2.42.0","status":"affected","versionType":"semver","lessThan":"2.42.1"},{"version":"2.42.1","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118677","source_modified_at":"2026-10-28T18:59:49.747Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":"n8n","vendor":"n8n-io","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2.41.4"},{"version":"2.41.4","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118677","source_modified_at":"2026-10-28T18:59:49.747Z","fetched_at":"2026-10-28T20:58:01.013507Z","package":{"name":"n8n","ecosystem":null},"version":"2.42.1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118677","source_modified_at":"2026-10-28T18:59:49.747Z","fetched_at":"2026-10-28T20:58:01.013507Z","package":{"name":"n8n","ecosystem":null},"version":"2.41.4","basis":"first unaffected version stated in the CVE record"}],"cvss":5.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T18:59:49.747Z","modified_at":"2026-10-28T18:59:49.747Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-118677","fetched_at":"2026-10-28T20:58:01.013507Z","source_modified_at":"2026-10-28T18:59:49.747Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-cwm2-vhf5-27q9","tags":["vendor-advisory"]},{"source":"CVE List","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","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-28T18:59:49.747Z","content_hash":"f62fbd67cc7abfcb27ba29edabdf6f33b3c495a6c1b6cb5b451266abca164b0e"}}
