CVE-2026-69262Public exploitNetwork attack vector

Unauthorized flow deletion via type-blind permission check

Published Aug 4, 2026 · Updated Aug 4, 2026

Incorrect authorization in FlowiseAI Flowise before 3.1.3 allows remote authenticated users to delete unauthorized flow types via its API. The DELETE /api/v1/chatflows/:id route accepts either deletion permission, then resolves by ID and workspace without binding permission scope to the stored flow type. A user with one flow-type deletion permission can delete the other flow type in the same workspace, causing unauthorized configuration loss.
