II. Public POCs for CVE-2026-23536

# POC Description Source Link Shenlong Link
1 Feast (the open-source Feature Store) Feature Server through 0.58.0 exposes an unauthenticated POST /read-document endpoint that reads an arbitrary, caller-supplied file path with no authentication and no path validation. The read_document_endpoint handler passes the JSON `file_path` field straight to os.path.exists()/open() and returns the file contents in the JSON `content` field, so a remote, unauthenticated attacker can read any file readable by the server process (e.g. /etc/passwd, feature_store.yaml, cloud credentials). Unlike the store-mutating routes it carries no inject_user_details/permission dependency. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-23536.yaml POC Details
