Is this vulnerability remotely exploitable over the internet?

Yes, but only by authenticated clients who can reach the Chainlit API and submit Element updates. Those clients can then cause the server to issue HTTP requests to internal or restricted endpoints that might not be directly reachable from the internet.

What level of access does an attacker need to exploit this issue?

The attacker must be able to authenticate to the Chainlit instance and create or modify Elements that include a `url` property. No direct access to internal services is required, since the server acts as the requester.

What is the safest general fix pattern?

The most robust fix is to avoid using arbitrary user-supplied URLs for server-side fetches. Where such functionality is required, enforce strict allowlists of permitted hosts or services, implement thorough validation and address filtering, and block access to internal and metadata endpoints, combined with network egress controls.
