Unauthenticated users can run a public flow through the /api/v1/build_public_tmp route, and its files field is read by Langflow and fed into the LLM. The file path can point to any path the storage supports, including a local file or an S3 path, depending on the flow configuration.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-rcjh-r59h-gq37","publishedAt":"2026-06-16T17:36:00.000Z","cveId":"CVE-2026-48520","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langflow@< 1.10.0 (fixed: 1.10.0)"],"affectedPackageNames":["langflow"],"affectedPackageRefs":["pypi:langflow"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Langflow"],"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":0.00437,"epssCheckedAt":"2026-11-04T18:09:13.251Z","kevDateAdded":null,"advisoryAliases":["GHSA-rcjh-r59h-gq37"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-06-16T17:36:00.000Z","fixReleasedAt":"2026-06-09T18:47:47.559Z","daysToFix":-7,"fixCheckedAt":"2026-10-29T21:34:33.268Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"langflow","fixedVersion":"1.10.0","matchedVersion":"1.10.0","fixReleasedAt":"2026-06-09T18:47:47.559Z","daysToFix":-7,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:34:33.118Z"}]}}
