As a result, any authenticated low-privilege user or valid API key can read or delete document-store upsert history belonging to other users and other workspaces whenever the target chatflowId (which is exposed publicly in /chatbot/<chatflowId> share links) or row ids are known. The retrievable flowData and result fields contain embedding, record-manager and vector-store node configuration, including per-node paramValues. No patched version is available.","published":"2026-09-26T14:16:41.460","modified":"2026-09-26T14:16:41.570","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-jvx3-mjpw-r4gh"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/flowise-through-3.1.4-missing-authorization-via-upsert-history"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-26T14:16:41.570"}}
