Prior to 3.1.3, the CSVAgent in packages/components/nodes/agents/CSVAgent/CSVAgent.ts extracted attacker-controlled CSV data with file.split(',').pop() and interpolated it directly into executable Python as base64_string = \"${base64String}\" before calling Pyodide. The validatePythonCodeForDataFrame() denylist only checked later LLM-generated code and did not validate this initial code block. An authenticated attacker could inject a closing quote followed by Python code, use Pyodide's js bridge to load Node.js child_process, and execute arbitrary operating system commands as root in the Flowise container. This issue is fixed in version 3.1.3.","state":0,"publishedAt":"2026-08-04T15:39:39.166+00:00","modifiedAt":"2026-08-04T19:52:22.14+00:00","affected":[{"ecosystem":"Vendor product","name":"Flowise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FlowiseAI\",\n                    \"product\": \"Flowise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.1.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":"CRITICAL"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-vmv7-4m6c-3cg5","https://github.com/FlowiseAI/Flowise/pull/6499","https://github.com/FlowiseAI/Flowise/commit/f4e2794f6a576b94578f2fdafbf49c2fb304626c","https://github.com/FlowiseAI/Flowise/releases/tag/flowise%403.1.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-69255","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-69255","identifiers":["CVE-2026-69255"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
