📄 Flowise 3.1.3 Arbitrary Code Execution

Flowise version 3.1.3 suffers from an arbitrary code execution vulnerability. On Windows, the Custom MCP stdio environment variable validation uses case-sensitive comparison. Supplying "nodeoptions" bypasses the NODEOPTIONS denylist and allows arbitrary code execution via --require. Exploit Title...

CVE-2026-58057

Flowise before 3.1.3 is affected: a case-sensitive denylist for Custom MCP stdio environment variables allows bypass on Windows (case-insensitive env names). An authenticated user who can configure a Custom MCP node can inject NODE_OPTIONS --require to execute arbitrary code in the Flowise server...
