The extension collects user-entered and a Wayfair product URL and POSTs them to a hardcoded Slack webhook URL ([domain withheld]) belonging to an unknown third-party Slack workspace — not the publisher's own infrastructure. The CWS-disclosed collections include 'Personally identifiable information' and 'Location', and Slack is a well-known SaaS, so the destination isn't itself disqualifying; however, the data (user's + browsing URL) flows to whoever controls that Slack webhook token, which is opaque and unverifiable. The publisher's only other extension is flagged malicious (), the permhash cluster has 43% malware rate, and the product appears semi-functional (1292-day-old v0.1 with 2-star rating), raising the possibility this is a simple data-harvesting tool dressed as a price tracker rather than a genuine product.
