The route /api/v1/build_public_tmp executes any public flow given its flow ID, and the data.nodes[X].data.node.template.code.value field accepts arbitrary Python code from the JSON payload. The source states the impact as unauthenticated RCE on any deployment with a shareable playground, and tested on commit 2d67402b1dbaefcbce85a244d4a6cd5e4bda1cfe.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-v5ff-9q35-q26f","publishedAt":"2026-06-16T17:35:32.000Z","cveId":"CVE-2026-48519","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langflow@<= 1.9.1 (fixed: 1.9.2)"],"affectedPackageNames":["langflow"],"affectedPackageRefs":["pypi:langflow"],"affectedVendors":[],"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":0.00783,"epssCheckedAt":"2026-11-04T12:08:33.690Z","kevDateAdded":null,"advisoryAliases":["GHSA-v5ff-9q35-q26f"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-06-16T17:35:32.000Z","fixReleasedAt":"2026-05-01T18:57:22.383Z","daysToFix":-46,"fixCheckedAt":"2026-10-29T21:34:34.009Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"langflow","fixedVersion":"1.9.2","matchedVersion":"1.9.2","fixReleasedAt":"2026-05-01T18:57:22.383Z","daysToFix":-46,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:34:33.862Z"}]}}
