The POST /api/v1/node-custom-function endpoint lacks route-level authorization, so any authenticated user or API key can submit arbitrary JavaScript to the Custom JS Function node. When E2B_APIKEY is not configured, that code runs inside a NodeVM sandbox that can be escaped to reach the host process object and run system commands via child_process, giving authenticated remote code execution on the Flowise server host.","solution":"This issue has been patched in version 3.1.2.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-46442","publishedAt":"2026-06-08T16:16:41.347Z","cveId":"CVE-2026-46442","cweIds":["CWE-94"],"cvssScore":null,"cvssSeverity":null,"severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.1 (fixed: 3.1.2)"],"affectedPackageNames":["flowise"],"affectedPackageRefs":["npm:flowise"],"affectedVendors":[],"affectedVendorsRaw":["Flowise"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Flowise remote code execution through /api/v1/node-custom-function endpoint","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.3634,"epssCheckedAt":"2026-10-27T12:09:05.497Z","kevDateAdded":null,"advisoryAliases":["GHSA-9rvc-vf7m-pgm2"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:47:48.415Z","patchAvailable":true,"disclosureDate":"2026-06-08T16:16:41.347Z","capecIds":["CAPEC-242"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
