Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the mitigation for CVE-2025-8943 blocked -y and --yes flags on npx, but packages/components/nodes/tools/MCP/core.ts denied only PATH, LDLIBRARYPATH, DYLDLIBRARYPATH, and NODEOPTIONS by exact environment-variable name. Because npm reads configuration from npmconfig_* variables, setting npmconfigyes=true reproduced --yes behavior without using a blocked flag, causing npx to auto-install and execute the named package when a Custom MCP server launched. This issue is fixed in version 3.1.3.
