Security checks across malware telemetry and agentic risk

Overview

This skill does what it says: it helps upload user-specified local files to user-specified web pages, but users should be careful because uploads disclose those files to the destination site.

Use this only when you intentionally want to upload a specific file to a trusted website. Before running it, verify the destination domain, selector, and full resolved file path, and avoid uploading secrets, credentials, private documents, or unrelated workspace files unless that site is meant to receive them.

Finding
This skill instructs the agent to upload local files to arbitrary external web pages but does not warn that doing so can exfiltrate file contents, metadata, and sensitive filenames to third parties. The risk is amplified by examples that encourage absolute paths, workspace-relative files, and uploads to public sites, making accidental disclosure of local or workspace data more likely.
