Google Chrome Patch Highlights Security Risks of AI Browser Integration

Palo Alto Networks’ Unit 42 said AI assistants such as Gemini require elevated privileges and access to tabs, local files and core browser functions when integrated into browsers to perform tasks for users. That access could allow attackers to issue commands through an AI assistant, creating a new attack surface absent from traditional browsers.

Google patched a high-risk Chrome vulnerability in January. Research showed that a malicious extension could hijack the Gemini side panel and gain access to a user’s local files. Unit 42 said the patch demonstrated how deep integration between AI and browsers could amplify existing extension risks, requiring vendors to continually review permission boundaries and command-routing mechanisms.
