AI Browser Agents Face Critical Security Vulnerabilities Through Prompt Injection Attacks

New AI-powered browsers from OpenAI and Perplexity feature agents that can perform tasks autonomously by navigating websites and filling forms, but they introduce significant security risks. Cybersecurity experts warn that these agents are vulnerable to "prompt injection attacks" where malicious instructions hidden on webpages can trick agents into exposing user data or performing unauthorized actions. While companies have introduced safeguards, researchers note that prompt injection remains an unsolved security problem affecting the entire AI browser category.
