NVD description
Flowise through 3.1.4 contains missing route-level RBAC checks on chat message endpoints that allow low-privileged API keys to read and delete chat history. Attackers with valid but low-privileged API keys can access GET and DELETE chat message routes without required flow permissions to read chat histories, prompts, model responses, and delete messages.
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.
