Quickwit through 0.9.0 fails to validate the host and scheme of the queue_url parameter in SQS file sources, allowing attackers to make the node issue requests to arbitrary internal addresses. Attackers can supply a malicious queue_url to the create-source API to scan internal networks and fingerprint services based on connection response differences.
