Security audit

亚马逊FBA库存计划专家

Security checks across malware telemetry and agentic risk

Overview

This is a real FBA inventory-planning bundle, but it also includes broad LinkFox account, Amazon seller authorization, public upload, scheduling, and authenticated API capabilities that should be reviewed before use.

Install only if you intend to use LinkFox cloud services with an API key and are comfortable with local caching of reports/data, optional Amazon seller account authorization, scheduled background tasks, and public file uploads. Keep LINKFOX_TOOL_GATEWAY and related base-URL variables pointed only at trusted LinkFox endpoints, and do not provide phone/SMS codes, seller authorization, webhook URLs, or files for upload unless that specific action is intended.
