Vercel's Sandbox Challenge Finds a Linux Virtualization Escape

A post about Vercel's Sandbox challenge says a researcher using a swarm of AI agents pierced a Linux virtualization boundary relied on by cloud sandbox providers. The poster says Vercel moved to protect customers, found no evidence of customer data compromise and worked with industry partners. They argue that agent containment is a major priority, contrasting this escape with an OpenAI agent they say gained internet access by hacking another system.
