Prior to 3.1.0, an improper mass assignment (JSON injection) vulnerability in the account registration endpoint of Flowise Cloud allows unauthenticated attackers to inject server-managed fields and nested objects during account creation. This enables client-controlled manipulation of ownership metadata, timestamps, organization association, and role mappings, breaking trust boundaries in a multi-tenant environment. This vulnerability is fixed in 3.1.0.","state":0,"publishedAt":"2026-04-23T19:12:26.765+00:00","modifiedAt":"2026-04-23T19:44:53.201+00:00","affected":[{"ecosystem":"Vendor product","name":"Flowise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FlowiseAI\",\n                    \"product\": \"Flowise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-48m6-ch88-55mj"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-41267","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-41267","identifiers":["CVE-2026-41267"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
