Since the Python environment (Pyodide, a tool that runs Python in JavaScript) can access JavaScript functions like `eval` and file operations, an attacker can break out of the Python code, run JavaScript commands, and gain full control of the server, even without authentication.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-4j8x-x6v7-w9rq","publishedAt":"2026-08-04T17:43:48.000Z","cveId":"CVE-2026-69264","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":[],"issueType":"vulnerability","affectedPackages":["flowise-components@<= 3.1.2 (fixed: 3.1.3)","flowise@<= 3.1.2 (fixed: 3.1.3)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Flowise","Pyodide","pandas"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-08-04T17:43:48.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality","availability"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
