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.","published_at":"2026-08-04T16:54:36.893000Z","last_modified_at":"2026-09-14T19:24:10.777000Z","cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":8.7,"cvss_v4_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","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-184"],"nvd_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"],"vuln_status":"Analyzed","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-08-04T17:40:38.286493Z","updated_at":"2026-09-16T00:00:38.137528Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"flowiseai","vendor_name":"FlowiseAI","product_slug":"flowise","product_name":"Flowise","version_start":"< 3.1.3","version_start_inclusive":true,"version_end":"< 3.1.3","version_end_inclusive":true,"cpe23_uri":"cve5:flowiseai:flowise:< 3.1.3:< 3.1.3"},{"vendor_slug":"flowiseai","vendor_name":"FlowiseAI","product_slug":"flowise","product_name":"Flowise","version_start":null,"version_start_inclusive":null,"version_end":"3.1.3","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:flowiseai:flowise:*:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-xc48-889x-5qmw","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/FlowiseAI/Flowise/pull/6471","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FlowiseAI/Flowise/commit/a4c4e4988cded15edf725e762560575b889ae351","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-08-04T16:54:36.893000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-08-04T18:41:38.297163Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-04T18:41:38.297163Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-08-04T18:41:38.297163Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-09-16T00:00:38.137528Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-09-16T00:00:38.137528Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-09-16T00:00:38.137528Z","label":"CVSS score revised","source":"nvd"}]}
