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, LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and NODE_OPTIONS by exact environment-variable name. Because npm reads configuration from npm_config_* variables, setting npm_config_yes=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.","state":0,"publishedAt":"2026-08-04T16:54:36.893+00:00","modifiedAt":"2026-08-04T17:20:39.789+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:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-xc48-889x-5qmw","https://github.com/FlowiseAI/Flowise/pull/6471","https://github.com/FlowiseAI/Flowise/commit/a4c4e4988cded15edf725e762560575b889ae351","https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-69263","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-69263","identifiers":["CVE-2026-69263"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
