Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed cloud client for ecommerce content, but it sends an API key and user-provided listing data to a configurable HTTP endpoint without host or HTTPS validation.

Install only if you are comfortable sending product, listing, and brief content to the Yufluent service under your TOKENAPI_KEY. Set TOKENAPI_BASE_URL deliberately, avoid non-HTTPS remote endpoints, and treat the API key as a billing credential that should not be shared with untrusted local services.

Vague Triggers

Medium
Confidence
79% confidence
Finding
The trigger phrases are broad enough to match common ecommerce writing requests, which can cause the agent to invoke this external cloud-backed skill when the user may only want local assistance. That increases the chance of unneeded data transfer to a third-party service and can lead to overscoped tool use without clear user intent.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The code defaults to an HTTP endpoint (http://localhost:8080/v1) and also accepts arbitrary base URLs without warning, while attaching a Bearer API key to requests. If used across a network or with a non-local insecure endpoint, credentials and payload contents can be intercepted or modified in transit.
