Hackers Could Bypass ChatGPT Lockdown Mode to Steal Conversations Without Users Knowing
Matched: medical
Check Point Research found a flaw letting attackers bypass ChatGPT's Lockdown Mode via a hidden popup trick in HTML code previews. Exploiting nested iframes, attackers could steal full chat histories, display fake update windows to push malware, or capture login credentials. In the ChatGPT Classic desktop app, no user interaction was needed. OpenAI removed the popup permissions on September 18, 2026, fully closing the vulnerability.
Now ChatGPT Chrome Extension Can See and Analyze the Content in Open Tabs
Matched: health
OpenAI's ChatGPT Chrome extension now reads content across open tabs and performs browser tasks like comparing products, filling forms, sending messages, and organizing tabs. Available on all plans, it works in Edge, Brave, and Opera too. Tasks can run in the background. Security concerns include access to signed-in accounts, sensitive data exposure, and prompt injection risks. Users should install only from official sources and limit signed-in access during use.
