This vulnerability only affects deployments that explicitly install the computer-use package, not standard n8n installations. An attacker with access to the system could potentially read files, modify data, or communicate over the network from within the agent process.","solution":"The issue has been fixed in n8n versions 2.29.8 and 2.30.1. Users should upgrade to one of these versions or later. The fix adds sandbox enforcement on Linux via bubblewrap and disables the shell tool entirely when a working sandbox cannot be established. An explicit opt-out flag (`--dangerously-disable-shell-sandbox`) is available for deployments that require unsandboxed shell access. As temporary workarounds if upgrading is not immediately possible, administrators should disable or avoid deploying the computer-use package on Linux or Windows hosts, and restrict access to the n8n instance to fully trusted users only.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-fpg6-x68q-5793","publishedAt":"2026-07-22T22:28:24.000Z","cveId":"CVE-2026-65590","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["n8n@< 2.29.8 (fixed: 2.29.8)","n8n@>= 2.30.0, < 2.30.1 (fixed: 2.30.1)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["n8n","@n8n/computer-use"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-07-22T22:28:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
