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.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. The public collections list a Nuclei template for it.
