CVE-2026-100610

Flowise through 3.1.4 exposes GET /api/v1/upsert-history/:id and PATCH /api/v1/upsert-history without route-level permission checks, and the backing service performs no workspace or ownership validation. getAllUpsertHistory() returns UpsertHistory rows selected solely by an attacker-supplied chatflowid, and patchDeleteUpsertHistory() deletes rows by an attacker-supplied array of record UUIDs. 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.
