CVE-2026-56268Public exploitNetwork attack vector

Cross-workspace configuration disclosure via unscoped database query

Published Jun 22, 2026 · Updated Jun 22, 2026

Incorrect authorization in Flowise before 3.1.2 allows remote authenticated users to read other workspaces' chatflow configurations. The getChatflowByApiKey service adds unprotected chatflows to its database query without filtering their workspace and returns complete ChatFlow entities. Exploitation requires a valid API key in one workspace and an unprotected chatflow in another; it does not grant configuration write access.
