## AI overview

404 Media reports that Meta teams rushed to address virtual machine escape vulnerabilities before Muse launched. At least one flaw could have allowed a Muse user to access sensitive internal Meta databases. Internal posts describe efforts to restrict agents' access and network destinations, while a security researcher questions the risks of hosting user-controlled virtual machines within Meta's production environment. Meta says its security work continues through internal testing, red teaming and a bug bounty program.
