NVD description
An Authentication Bypass vulnerability exists in Flowise version 1.8.2. This could allow a remote, unauthenticated attacker to access API endpoints as an administrator and allow them to access restricted functionality.
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.
