I noticed that apparently users can grab people's IPs by linking a photo here:
because it links to another website. Nobody even needs to press any links. You can verify that it works here: iplogger.org [slash] logger [slash] wXbB39Ov09sH
I also noticed that the linked media can run untrusted scripts from external webpages. For example if I link a youtube video like this:
it tries to run scripts from the following websites:
…sociopathcommunity.com
…doubleclick.net
…google.com
…googletagmanager.com
…googlevideo.com
…gstatic.com
…jnn-pa.googleapis.com
…youtube.com
Couldn't someone link mirrored media here from their own phishing website that runs their own javascript that can be used to dox or grab cookies from people if they don't have a noscript extension on their browser?
