Description
A security issue was discovered in the Feast Feature Server's `/read-document` endpoint that allows an unauthenticated remote attacker to read any file accessible to the server process. By sending a specially crafted HTTP POST request, an attacker can bypass intended access restrictions to potentially retrieve sensitive system files, application configurations, and credentials.
