NVD description
Flowise through 3.1.4 contains an insecure direct object reference vulnerability in the OpenAI Assistants integration that allows authenticated attackers to access credentials belonging to other workspaces by supplying an arbitrary credential UUID to Assistants endpoints without workspace ownership verification. Attackers can enumerate cross-workspace assistant metadata, retrieve file and vector store listings, and upload files into victim workspaces by exploiting the missing workspace-scoped authorization check in the credential lookup logic.
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.
