Is this vulnerability remotely exploitable?

Yes, if the Flowise instance is reachable over the network where an attacker resides (for example, if it is exposed to the internet or accessible from a shared internal network), the attacker can call the affected endpoints without authentication.

Does an attacker need valid credentials or an account to exploit this?

No. The core issue is that these endpoints are whitelisted from the global authentication middleware, allowing completely unauthenticated access as long as the attacker can reach the API over the network.

What is the safest general fix pattern for this type of issue?

Ensure that all security-sensitive routes—such as those that manage containers, configuration, or tokens—are protected by default authentication and authorization middleware. Avoid global whitelists for privileged endpoints and instead rely on explicit, centralized security controls that are applied uniformly.
