An attacker with access to a vulnerable chatflow prediction endpoint (/api/v1/prediction/{flowId}) can inject arbitrary Cypher executed against the connected Neo4j database, enabling data exfiltration, modification, deletion, and schema discovery. Exploitation requires a chatflow using the Graph Cypher QA Chain node, a Chat Model, and a Neo4j Graph node with valid credentials.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-28g4-38q8-3cwc","publishedAt":"2026-04-16T21:54:26.000Z","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","Neo4j","ChatOpenAI"],"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-28g4-38q8-3cwc"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-04-16T21:54:26.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
