NVD description
Flowise is a drag & drop user interface to build a customized large language model flow. In version 3.0.5, a Server-Side Request Forgery (SSRF) vulnerability was discovered in the /api/v1/fetch-links endpoint of the Flowise application. This vulnerability allows an attacker to use the Flowise server as a proxy to access internal network web services and explore their link structures. This issue has been patched in version 3.0.6.
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.
