An authenticated user can set require.builtin to [\"*\"] and re-enable child_process and fs, running arbitrary system commands as root on the Flowise server. The flaw is reached through the route in packages/server/src/routes/node-custom-functions/index.ts and the executeCustomNodeFunction() service in packages/server/src/utils/executeCustomNodeFunction.ts.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-3769-jgqc-cxm7","publishedAt":"2026-08-04T15:29:12.000Z","cveId":"CVE-2026-69254","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise-components@<= 3.1.2 (fixed: 3.1.3)","flowise@<= 3.1.2 (fixed: 3.1.3)"],"affectedPackageNames":["flowise-components","flowise"],"affectedPackageRefs":["npm:flowise","npm:flowise-components"],"affectedVendors":[],"affectedVendorsRaw":["Flowise"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00691,"epssCheckedAt":"2026-11-04T12:08:33.434Z","kevDateAdded":null,"advisoryAliases":["GHSA-3769-jgqc-cxm7"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-08-04T15:29:12.000Z","fixReleasedAt":"2026-06-25T10:35:37.031Z","daysToFix":-40,"fixCheckedAt":"2026-10-29T21:32:22.973Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"flowise-components","fixedVersion":"3.1.3","matchedVersion":"3.1.3","fixReleasedAt":"2026-06-25T10:35:37.031Z","daysToFix":-40,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:32:22.823Z"},{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.3","matchedVersion":"3.1.3","fixReleasedAt":"2026-06-25T10:41:14.612Z","daysToFix":-40,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:32:22.823Z"}]}}
