Is Pinned ChatGPT safe?

Medium risk

Pinned ChatGPT injects hidden affiliate iframes on whitelisted sites and sends the current site URL to trendupdeal.com.

After a delay, Pinned ChatGPT fetches remote configuration from www.dreamhov.de that defines which sites to target and what iframe HTML to use. On matching sites, after a user click, it builds a hidden iframe URL for www.trendupdeal.com/goto.php containing the current site's origin. Its background code also removes X-Frame-Options and Content-Security-Policy headers from subframes, which supports the iframe insertion path.
