The endpoint is designed to be public but incorrectly accepts attacker-supplied flow data containing arbitrary Python code, which gets executed without sandboxing when the flow is built. An attacker only needs to know a public flow's ID and can exploit this to run any code on the server.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-vwmf-pq79-vjvx","publishedAt":"2026-03-17T20:05:05.000Z","cveId":"CVE-2026-33017","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["langflow@<= 1.8.1"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Langflow"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-03-17T20:05:05.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":["AML.T0010"]}}
