Overview
chainlit is a Build Conversational AI.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the /project/element update flow when the SQLAlchemy data layer backend is configured. An attacker can cause the server to send arbitrary HTTP requests to internal network services or cloud metadata endpoints by supplying a user-controlled URL, and can store the retrieved responses through the configured storage provider. This is only exploitable if the SQLAlchemy data layer backend is enabled and the attacker is authenticated.
