Summary
An SSRF vulnerability in Chainlit before version 2.9.4 allows an authenticated attacker to make arbitrary HTTP requests from the server to internal network services or cloud metadata endpoints via a user-controlled URL in an Element during the /project/element update flow with the SQLAlchemy data layer backend.
Risk Assessment
An attacker can access internal network resources, such as cloud instance metadata endpoints, potentially leading to sensitive data leakage or further escalation within the infrastructure.
Recommendation
Immediately upgrade Chainlit to version 2.9.4 or later, which includes a fix for the SSRF vulnerability.
Original NVD description (English source)
Chainlit versions prior to 2.9.4 contain a server-side request forgery (SSRF) vulnerability in the /project/element update flow when configured with the SQLAlchemy data layer backend. An authenticated client can provide a user-controlled url value in an Element, which is fetched by the SQLAlchemy element creation logic using an outbound HTTP GET request. This allows an attacker to make arbitrary HTTP requests from the Chainlit server to internal network services or cloud metadata endpoints and store the retrieved responses via the configured storage provider.
