Prior to 1.9.0, any authenticated Langflow user can achieve Remote Code Execution (RCE) on the server by adding an MCP server with the \"Stdio\" transport. The user-supplied command field is passed directly to bash -c \"exec {command}\" with zero validation, no allowlisting, and no sandboxing. The command executes immediately when the server list is fetched. Additionally, the env field allows arbitrary environment variable injection (e.g., LD_PRELOAD, PATH override). This vulnerability is fixed in 1.9.0.","state":0,"publishedAt":"2026-10-05T20:46:18.854+00:00","modifiedAt":"2026-10-06T18:20:28.495+00:00","affected":[{"ecosystem":"Vendor product","name":"langflow","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"langflow-ai\",\n                    \"product\": \"langflow\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.9.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/langflow-ai/langflow/security/advisories/GHSA-7w94-79vh-5mr2","https://github.com/langflow-ai/langflow/security/advisories/GHSA-w794-rj3p-xv45","https://github.com/langflow-ai/langflow/pull/12290","https://github.com/langflow-ai/langflow/commit/efbc4a16e639409d938a4883463d27ef0bc637a0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105740","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105740","identifiers":["CVE-2026-105740"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
