Recent research has revealed new attack techniques that can exploit webmail services by allowing malicious content in emails to escape their intended boundaries. This vulnerability affects major platforms like Outlook, Gmail, Fastmail, Proton Mail, Yahoo Mail, and AOL Mail. Attackers can use these methods to capture user passwords, take control of third-party accounts, leak sensitive tokens, and manipulate user interface actions. This is particularly concerning as it could allow for unauthorized access to personal information and interactions with AI tools that read emails. The implications for user privacy and security are significant, as these attacks can bypass traditional defenses that many users rely on.
