The FILE-STORAGE:: check in replaceInputsWithConfig in packages/server/src/utils/index.ts uses .includes() rather than .startsWith(), so an attacker can embed the keyword in a string and skip the isParameterEnabled() check. This lets the attacker set NODE_OPTIONS through the Custom MCP node, which does not block it, and run arbitrary code with root privileges in the container. The attack requires a single HTTP request, plus API Override enabled and a public chatflow containing an MCP tool node.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-cvrr-qhgw-2mm6","publishedAt":"2026-04-16T21:46:39.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise-components@<= 3.0.13 (fixed: 3.1.0)","flowise@<= 3.0.13 (fixed: 3.1.0)"],"affectedPackageNames":["flowise-components","flowise"],"affectedPackageRefs":["npm:flowise","npm:flowise-components"],"affectedVendors":[],"affectedVendorsRaw":["Flowise","Custom MCP node"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-cvrr-qhgw-2mm6"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-04-16T21:46:39.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
