"Researchers: LinkedIn, Instagram Vulnerable to Preview-Link RCE Security Woes"

Independent researchers have discovered that link previews in popular chat apps on iOS and Android are a firehose of security and privacy issues.   Facebook Messenger, LINE, Slack, Twitter Direct Messages, Zoom, and many others are at risk. In the case of Instagram and LinkedIn, it is even possible to execute remote code on the companies’ servers through the feature.  According to the researchers, link previews can leak IP addresses, expose links sent in end-to-end encrypted chats, and have been caught “unnecessarily downloading gigabytes of data quietly in the background.”
