Are AI browsers worth the security risk? Why experts are worried
AI browsers are highly susceptible to prompt injection attacks, where threat actors can manipulate Large Language Models (LLMs) to bypass security controls and execute unauthorized actions. This vulnerability allows for sensitive data exfiltration by exploiting the LLM's inability to distinguish between trusted user commands and malicious instructions embedded in untrusted web content, effectively nullifying browser protections like the same-origin policy.
