Summary
On load, index.js schedules a setTimeout (~2s) that fetches the current origin's /profile endpoint, parses the returned HTML, extracts a.flag-value element (falling back to the entire page body), and issues a POST to /addPost with the extracted content as JSON. The behavior fires unconditionally without user interaction, uses the embedding page's authenticated session to read private profile data, and then publishes that data through a state-changing endpoint on the same origin. The package name ("feed-widget-helper") and package.json are placeholders: description, author, repository, and keywords are all empty, and the shipped code has no relation to any feed-widget functionality. The shape is a same-origin CSRF/exfiltration payload rather than a helper library.
