OpenAI Acknowledges Permanent Vulnerability of AI Browsers to Prompt Injection Attacks

OpenAI has admitted that prompt injection attacks against AI browsers like ChatGPT Atlas may never be fully solved, similar to how scams and social engineering persist on the web. The company is deploying an LLM-based automated attacker trained through reinforcement learning to proactively discover and patch vulnerabilities before they're exploited in the wild. Despite these defensive measures, experts warn that agentic browsers currently pose significant risks due to their high access to sensitive data combined with moderate autonomy, questioning whether their value justifies their risk profile.
