NVD description
Flowise through 3.1.4 contains a missing authorization vulnerability that allows authenticated workspace members to perform unauthorized document store operations by accessing unprotected mutation endpoints. Attackers holding only view-level permissions can send direct HTTP requests to the upsert and refresh document store routes to trigger document ingestion, refresh vector database contents, consume embedding API credits, and modify knowledge bases used by downstream chatflows.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Flowise off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
